  • First Post: Feb 17, 2017 3:36am Feb 17, 2017 3:36am
Hello, I created an EA from FXPRO QUANT but i cannot fulfill 1 condition whatever i do.
i.e. Lot size has to be increased in steps, If previous trade related to that magic number is a profit.
And lot size should reset when a loss is made.
Can anyone please help?

I think it would help if you could indicate more specific information about your desired lotsize calcuation method.
-When to increase lots? How much?
-When to decrease lots? How much?
-When to reset?

Etc etc.

Without this information we all can only guess what you are looking for.

I am sorry attaching the EA here.

1)I want to Double lot size ( in steps or fixed addition of lot size) if previous trade on this magic number is a profit.
2) Reset lotsize if last trade of this magic number is a loss.

Any help is very much appreciated.

I tried to put codes i found online but no success, it always results in some error when compiling and can never be fixed

Mabe find a working EA and have it modified to trade with the conditions you want? This is not a good code base to start from.
This code cannot make a sell order. This code cannot make a 1st order - there must be Order History before it can begin functioning.
if(OrdersHistoryTotal() > 0)
{
LastTradeResult(Symbol());
result = OrderSend(Symbol(), OP_BUY,Dynamic_Lots, Ask, Slippage, sl, tp, "FxProQuant" + "(" + WindowExpertName() + ") " + TradeComment, MAGIC_NUM);
}
I started cleaning it up, but decided this is not something I'm interested in doing. It does compile without error now, and the magic number is the same in all the functions, where it wasn't before.

Edit: Sorry, looked at the post and saw I uploaded the wrong file. Here's the right one:

Here is yet another signal crossing EA. It doubles the lots as soon as there is a winning sequence. It's generic / buy, sell or both. Includes lots of debug capability so you can edit it and fix it yourself.

An here it is edited to match http://www.forexfactory.com/showthread.php?t=643134.

Thanks a lot brother. Really aprreciate your help. You are almost so close to what I have asked for except 1 minor change, not sure if it is even possible or not.

As I said, lot size should increase in steps or double after every profit trade. But the EA which you posted only takes double lot for 2nd trade only. 3rd trade will be reset again to minimum lot.

go on down to 'Get Lots', starts on line 411. Change
if( profitSequenceCount > 0 )
{
tradingLots *= 2;
}
to:
if( profitSequenceCount > 0 )
{
tradingLots *= (profitSequenceCount+1);
}
and they will be multiplied with each additional profitable trade by 2,3,4,5, etc. If you want it to be by 2, 4, 6, 8, 10, change to:
if( profitSequenceCount > 0 )
{
tradingLots *= (profitSequenceCount*2);
}
and finally, for 2, 4, 8, 16, use:
if( profitSequenceCount > 0 )
{
tradingLots *= (MathPow(2,profitSequenceCount));
}
"3rd trade will be reset again to minimum lot" - change the If statement to:
if( (profitSequenceCount>0) && (ProfitSequenceCount<3) )

{quote} lot size should increase in steps or double after every profit trade. But the EA which you posted only takes double lot for 2nd trade only. 3rd trade will be reset again to minimum lot. it works only on Yen JPY pairs, when kept on EU/GU/USDCHF etc, it wont enter a trade as it shows a invalid stoploss error message
Posted a new version.
- I haven't seen it create a SL error, and I've ran it with ERUUSD for some time.
- There is even more accessible debug info. Click on the Seq text to cycle through all the debug statements (cannot do that in strategy tester, as the tester environment doesn't support events). Some will get first values with a new bar, and others with their first order. I set it to default to SL debug info.
Pay attention to these settings:
extern uint MAX_PROFIT_DOUBLE = 3; // Number of times lots will be doubled in a profitable sequence
extern uint MAX_LOSS_DOUBLE = 3; // Number of times lots will be doubled in a loosing sequence
these will multiply lots by 1, 2, 4, 8. I think akash14 wanted 2 and 0 for these values in the original spec. It looked to me like the 1 minute scalper wanted something along the lines of 1, 3.
extern int FAST_MA_PERIOD = 12;
extern int SLOW_MA_PERIOD = 48;
use 21 and 100 for the 1 minute scalping strategy.
//
Decided I didn't like that it only takes signals at the opening of a new bar, added this:
extern bool NEW_BAR_ONLY = false;
//
Found reason for invalid sl. changed
double minSLAmount = MathMax(MarketInfo(Symbol(),MODE_STOPLEVEL),(Point*_PointsInPip));
to
double minSLAmount = MathMax(MarketInfo(Symbol(),MODE_STOPLEVEL)*Point,(Point*_PointsInPip*minMultiplier)); // ensure not zero, at least 1 pip

Thanks for your hardwork mate. But the previous version was very appropriate per my need only with little changes needed.
- BuyandSell - Never worked as I needed it. I was using either "Buy only" or "Sell only" in the previous version you posted. And it was working perfect in 1 direction.
- SL cannot be changed no matter what i do in older version,also New version you just posted. Old version gives 1000pip SL on yen pairs.
- Both version EA's do no take a buy trade on EU,GU etc except yen pairs. "Sell Only" works. Sorry for not testing it in both directions earlier.

These are error messages i receive when on Buy only on EU with this EA.

I want only 1 thing in the older version bro. To take orders on other pairs and edit stoploss.

don't know what to think. I've got it running without error - I don't see any bad values displayed in the debug display: Here's a auto selection (got a 64 point SL) and a preset 5 pip SL. This is EUR/USD, 15 min strategy tester on Oanda. 21,407 bars in test, Profit Trades: 299, Loss Trades: 564. Initial Deposit: 10,000, ending at 10,040.82. All Buys.

// See post, just added another option, to take trade signals without waiting for the open of a new bar.

Found a reason for the sl error, is a risk of testing on weekend. Got zero from market info during the weekend, so the way I wrote it, it yeilded a 1 pip min SL. Today, market info returned 11, meaning 11 points (0.00011), and I saw the error. Seems to work OK now.
