## Opportunity in trading – General Forex Questions & Help

In forex each trader knows there is a gigantic chance to profit. In the multitrillion dollar money market, only a small amount of a penny distinction between two monetary forms can mean a huge number of dollars in benefit. Brokers utilized online visit rooms, both to design their moves and to boast a while later. The vast majority’s presentation to the money showcase is the point at which they travel. If anyone wants to come into forex market I would recommend them XeroMarkets broker. It’s one of the best broker out there with amazing trading facilities.

## Spreads – General Forex Questions & Help

The gap between buying and selling is called spread. It addresses brokerage advantage costs and replaces transactions charges. Spread is for the most part implied in pips – a rate in point, which implies fourth decimal place in currency reference. Following sorts of spreads are used as a piece of Forex Trading. I have the low trading spread from 0 pip with my broker XeroMarkets. It offers tight market spreads. This is a noteworthy good position for traders. As I have the most negligible spread I can extend my advantage level to a consistently expanding degree. You can trust them with your money.

## Mobile UX for a list of questions with editable answers?

As part of a larger app, I am designing a mobile UX for a fixed list of 30 questions that the app user can answer. The user can answer from 0 to 30 questions, averaging around 3 answers. They can edit/delete/add answers at any time, averaging around an edit every 5th session. Questions are short, one sentence each. Answers are long, 100 to 1000 characters each.

What UX pattern can I use for such list?

I have a few ideas, but I don’t like any of them:

1. A screen with a scrollable list of questions. A click on the question opens another screen with editable field for the answer. I don’t like this because it takes a lot of clicking back and forth to answer several questions.

2. A screen with a scrollable list of questions and answers. Answers are immediately below questions in editable fields. I don’t like this because it’s easy to loose track of short questions among a sheet of long answers. Also, will scrolling a bunch of editable fields be confusing?

3. A screen with a scrollable list of questions and answers. Answers are collapsed. Clicking on the question uncollapses the editable field that contains the answer. Same cons as #2. Plus if there are many answers, collapsing/uncollapsing each is annoying.

Are their UX best practices here? Anything you can suggest?

## ag.algebraic geometry – Some basic questions on quotient of group schemes

Let $$S$$ be a fixed base scheme and $$G, H$$ be group schemes over $$S$$. Since I am mainly interested in commutative group schemes over fields, we may assume that $$G,H$$ are commutative and $$S$$ is a field if this helps.

(1) Let $$f:Gto H$$ be a morphism of group schemes. To define the cokernel of this map, we need to choose which topology to work with. Some people use the fppf topology (as in van der Geer & Moonen’s book) and other people use the fpqc topology (as in Cornell-Silverman). My question is: what is the difference of those two topologies in terms of group schemes? Is fppf quotient and fpqc quotient of group schemes different? Which topology do people prefer when they are working with group schemes?

(2) Let $$H$$ be a (normal) closed subgroup scheme of $$G$$. I think there are at least three plausible definitions of the quotient $$G/H$$:

1. Categorical quotient: Since $$H$$ naturally acts on $$G$$, we can think categorical quotient $$G/H$$ of the action $$Htimes Gto G$$.

2. Fppf/fpqc quotient: $$G/H$$ represents the quotient of $$Hto G$$ in the category of fppf/fpqc sheaves.

3. Naive quotient: A group scheme $$G/H$$ with a surjective (wrt fppf/fpqc topology) map $$p:Gto G/H$$ such that kernel of $$p$$ is the inclusion $$Hto G$$

Are they equivalent in some good situations? In van der Geer & Moonen’s book, it is proved that a fppf quotient is also a categorical quotient. But I cannot find proof nor prove other directions.

context of the question (2): Let $$f:Ato B$$ be an isogeny of abelian varieties with kernel $$ker f$$. Then we have the dual exact sequence $$0to widehat{B}to widehat{A}to widehat{ker f}to 0$$. In Milne’s book on abelian variety, to prove the dual exact sequence, consider $$0to ker fto Ato Bto 0$$ as an exact sequence in the category of commutative group schemes over a field and use a long exact sequence with $$text{Hom}(-, mathbb{G}_m)$$. To use the long exact sequence, we need to prove $$B$$ is $$A/ker f$$ as a fppf/fpqc quotient (In fact I don’t know which topology to work with. This is why I ask the question (1)…). However, I only know that $$B$$ is the `naive quotient (3)’ $$A/ker f$$.

(3) Is the category of commutative group schemes over a field an abelian category? This statement is in Milne’s book on abelian variety, but I cannot find proof. The main point is existence of cokernel, i.e. representability of fppf/fpqc quotient. However, I only know the following theorem in Cornell & Silverman,

Theorem. Let $$G$$ be a finite type $$S$$-group scheme and let $$H$$ be a closed subgroup scheme of $$G$$. If $$H$$ is proper and flat over $$S$$ and if $$G$$ is quasi-projective over $$S$$, then the quotient sheaf $$G/H$$ is representable.

and this is too weak to prove our statement.

Also one more quick question: do you know any good reference dealing with sufficiently general group schemes? I know Shatz’s paper in Cornell-Silverman, Tate’s paper in Cornell-Silvermann-Stevens, and Stix’s lecture note, but they focus on finite flat group schemes. Also, I know some other articles & books which mainly focus on affine algebraic groups. Are there some more general references?

Thank you for reading my stupid questions.

## android – MVVM construction questions

I am trying to understand how MVVM works. Here are two examples (in Andrdoid) on how I understand it should work, please tell me if I understood correctly.

I currently want to make a list of radiobutton “Sex” with currently two possible values (Male, female).
I expect it to change to “Gender” and three possible values (Male, female, other).
I have the label as a TextView in my View that references the ‘label’ field of my viewModel. The label of my view model itself is referencing a field of my Model. Right ?
Also I should write the view as able to print a list of radio buttons from a table. That way, if I add a sex/gender, the View does not have to change.
What I am wondering is where this list “Male, Female” should be stored. Is it in the ViewModel or is it in the Model ? If this list is stored in a database, who should extract it ? The ViewModel or the Model ?

I have a “new password” field. The password have to respect certain conditions (length, special numbers…). How are those condition checking handled ?
The View will contain the EditText field password. When the user types the password, the view calls the ViewModel which itself will call the Model to check. If the password doesn’t fit, the model will return one or more warning values (length_too_short, no_special_char), the viewModel will then translates those warnings (“The password has to be 8 characters minimum”, “At least one special character”) and will call the View to show password error (the password field becomes red and under it the view writes the error message it receives).

## Weekly Trading Forecasts On Major Pairs (May 12 – 16, 2014) – General Forex Questions & Help

Here’s the market outlook for the week:

EURUSD

Dominant bias: Bullish

The dominant bullish bias still exists in this market, but it is seriously under threat.

The price attempt to reach the resistance line at 1.4000 failed, and the price got corrected significantly. Should price test the support line at 1.3800 or cross it to the downside, then the bullish bias would be rendered completely useless. Until that happens, it might be assumed that the price could rally i.e. if it could maintain its presence above the support level at 1.3800.

USDCHF

Dominant bias: Bearish

The outlook here is bearish, though the situation looks very precarious. The bulls have been very active recently: the bears have been subjugated and they need to prevent the price from remaining above the resistance level at 0.8800. The inability of the price to fall back below the aforementioned resistance level would result in the bearish outlook being rendered invalid. The invalidation would be especially strong when the price succeeds in challenging the resistance level at 0.8850.

GBPUSD

Dominant bias: Bullish

The bullish bias is still in place, but the price has been unable to cross the distribution territory at 1.7000 to the upside. In fact, the price has been consolidating to the downside for the past few days. The accumulation territories 1.6900 and 1.6850 have a job to do – they have to prevent the price from slashing though them and closing below them successively. This is the only thing that can keep the dominant bias intact. As long as the price is unable to breach those accumulation territories to the downside, it could be expected that price would rally from this point.

USDJPY

Dominant bias: Bearish

The recent equilibrium phase on this currency trading instrument has resulted in a slow southward propensity. However, the pair has met a great challenge at the demand level of 101.

50. The demand level has been tested several times, but there is a need for the price to breach it to the downside so that the southward move could continue.

EURJPY

Dominant bias: Bearish

The sudden weakness in the Euro has resulted in a Bearish Confirmation Pattern in the chart. Short trades are currently recommended. The cross should be trading below the price zone at 140.50, as it goes towards the price zone at 140.00. On the other hand, there might be some short-term rally from the aforementioned demand level.

This forecast is concluded with the quote below:

“If I tell you how I would manage that [\$100,000,000] now, I would no longer have a competitive edge.” – Perry Kaufman

No matter what your trading results have been in the past, trading remains one of the best ways to the ultimate attainment of financial freedom. During the recent global credit crunch, many people became fearful of the future, because economic crises sometimes compel good organizations to dismiss their responsible workers.

Many people did not realize this until it happened to them. They thought they only needed to work hard, and their job would be secure, and they would enjoy the ensuing financial security. But after the myth has been busted, many people became so anxious about a poor financial future and the effects it could have on their family.

Then many people started seeing trading as a great option: you can trade successfully anywhere, as long as you have access to a good internet connection and then enjoy financial security. The riches inherent in the markets are limitless, though it would be realistic to walk towards this gradually. Please renew your determination and partake in the journey to financial freedom.

‘Learn from the Generals of the Markets’ is a groundbreaking book.

For those who want to attain success by trial and error, it would take many years of harrowing experience to attain success. Nevertheless, for those who are guided by the principles adopted and revealed by the traders who are already victorious, the learning curve can be sped up and the journey made smoother. This means that it will take a far shorter period to attain success if you learn from the industry experts.

## Weekly Trading Forecasts On Major Pairs (May 19 – 23, 2014) – General Forex Questions & Help

Here’s the market outlook for the week:

EURUSD

Dominant bias: Bearish

This currency trading instrument has been bearish since last week. From a high of 1.3993, the price dropped by over 340 pips, reaching the support line at 1.3650. The support line has brought about a temporary halt in the bearish journey. This halt resulted in an upward bounce that has taken the price above the support line at 1.3700. The support line at 1.3750 should act as a barrier to further rally in the context of a downtrend. The bearish journey is supposed to continue when the price breaks the support line at 1.3650 to the downside, targeting another support line at 1.3550.

USDCHF

Dominant bias: Bullish

The current upward move has been the strongest trending move on the USD/CHF since April 2014. From a low of 0.8700, the price skyrocketed by over 250 pips, topping at the resistance level of 0.8950. There has been a short-term pullback which has been challenged at the support level of 0.8900. In case of more determined bears’ machination, the pullback could also be challenged at the support level of 0.8850. Generally the price ought to go further upwards, breaking the resistance level at 0.8950 to the upside as it goes towards another target at the resistance level at 0.9050.

GBPUSD

Dominant bias: Bearish

The pair gave way to gravity as well: it went down toward the accumulation territory at 1.6750 before the price experienced some shallow rally. The rally is seen as a temporary thing in the context of a downtrend. It is something that allows the bears to sell short at a better price. The next target is at another accumulation territory of 1.6650, which could be reached within the next several trading days.

USDJPY

Dominant bias: Bearish

There is a confirmed bearish outlook on this market, though the bearish run is not as strong as other JPY pairs. There is also a recalcitrant demand level at 101.50. This demand level has succeeded in rejecting further bearish move – it did that last week and this week. The price needs to breach the demand level to the downside and close below it, for the bearish outlook to continue o be valid.

EURJPY

Dominant bias: Bearish

This cross is in a downtrend and it is currently challenging the demand zone at 139.00. The demand zone has a high probability of being breached to the downside. When this happens, the price could target another demand zone at 138.00.

This forecast is concluded with the quote below:

## Weekly Trading Forecasts On Major Pairs (June 16 – 20, 2014) – General Forex Questions & Help

Here’s the market outlook for the week:

EURUSD

Dominant bias: Bearish

In a slow and tardy manner, this pair has been trending downwards. The movement is tardy because consolidation phases can be perceived in the market; yet it can also be clearly seen that the bears dominate the market. There is a shallow rally at the moment, which ought to be contained at the resistance lines of 1.3600 and 1.3650 respectively. This is necessary for the bearish trend to continue, because any movement above the resistance line would mean the end of the bearish bias.

USDCHF

Dominant bias: Bullish

It is expected that this currency trading instrument close above the strong psychological resistance level at 0.9000. This is a must – for the bullish outlook to continue to be valid. The market breached the resistance level several times this week and last week, but it is was unable to stay above it. This inability to close above the resistance line or go southward has led to a recent sideways movement. This is what would happen eventually: should the price fail to close above the resistance level at 0.9000 and go further towards the resistance level at 0.9050, another strong bearish bias would start. The USD may not reach parity with the CHF as soon as we think.

GBPUSD

Dominant bias: Bullish

There has been a significant upwards surge on this market. The price was bullish last week, and it experienced serious volatility earlier this week. From the accumulation territory at 1.6750, the Cable rallied by more than 240 pips. The distribution territory at 1.7000 is thus an easy target. This is a great psychological zone, and should the price succeeded in closing above it, the next target would be the accumulation territory at 1.7100. However the possibilities of pullbacks along the way cannot be ruled out.

USDJPY

Dominant bias: Bearish

The USD/JPY has become bearish, going downwards from the supply level 102.50. The current rally in the price may be another opportunity to sell short; provided the rally does not take the price above the supply level at 102.50. Should the price go further southward, it might reach the demand levels at 101.50 and 101.00.

EURJPY

Dominant bias: Bearish

This is also a bear market. The price has bounced up from the demand zone at 138.00, but this is supposed to be limited. The price may soon fall downwards again, testing that support zone, even breaking it to the downside.

This forecast is concluded with the quote below:
