- Account Balance * percent = RISK = (OrderOpenPrice - OrderStopLoss)*DIR * OrderLots * DeltaPerlot (Note OOP-OSL includes the SPREAD)
- Do NOT use TickValue by itself - DeltaPerlot
- You must also check FreeMargin to avoid stop out

double Spread=MarketInfo(Symbol(),MODE_SPREAD)/Q; double Risk=(RiskPercent*AccountEquity())/100;//this means if your balance 1000$ & RiskPercent=10% >> you going to risk 100$ double lot=Risk/((StopLoss+Spread)*MarketInfo(Symbol(),MODE_TICKVALUE)*Q);//Make Sure to Define Your StopLoss & Q=10 in 5 digits or Q=1 in 4 Digits

**yousefh:**, read the comment in my DeltaPerlot. Do NOT use tick value by itself.

Sorry its not good

Ok i see your point, so here is my logic and calculation how i calculate the RISK %

Which in MQL4 code looks like this:

extern double MYSTOPLOSS = 50; // CUSTOM SL SIZE IN PIPS AFTER THE STOPLEVEL extern double RISK =2; // 2% ACCOUNT RISK double LOT =(AccountEquity()*RISK)/(100*(MarketInfo(Symbol(),MODE_STOPLEVEL)+MYSTOPLOSS)* Point *100000 );

A simple 1 liner, nothing complicated, now please help me insert that DELTA stuff that you have been talking about, i know the formula is not complete so please help me.And please note that my account is in EURO so in most cases its the basic currency.

**Proximus:**Help me please quick, I would like to finish this project before X-mas :)

Yes i did, but i dont understand how you fit that into my equation, you said you need this:

MarketInfo(pair, MODE_TICKVALUE) / MarketInfo(pair, MODE_TICKSIZE)But i dont understand how this helps my equation, because dividing these two numbers will give a big number instead of the ticksize...

Perhaps looking at it from a different angle might help.

WTF guys, shouldnt that be** TICKVALUE * TICKSIZE **instead of** TICKVALUE /TICKSIZE** ? I think there is a big mistake there

Just made a quick indicator which shows separate values, i guess the TICKVALUE * TICKSIZE is the appropriate one...

And note the demo account is in EUR so that is the base currency, while i did the same test with a USD account and there the POINT was equivalent to TICKVALUE * TICKSIZE because it measures the quote currency value.

**Files:**

If i have understand the question right this will do the job for you.

for( i=0; i<=ot; i++ ) for( z=0; z<=10; z++ ) { if( long_orders_array_ATF[i][z] > 0 ) for (zz=0; zz<=10; zz++) { OrderSelect(zz,SELECT_BY_POS,MODE_TRADES); if (OrderTicket()==long_orders_array_ATF[i][z]) zz=ot+2; if (ot+2<=zz) long_potencial_loss = (OrderLots() * (OrderOpenPrice() - OrderStopLoss()))*100000; long_sum_potencial_loss = long_sum_potencial_loss + long_potencial_loss; } } ... lot_size = ((((free-long_sum_potencial_loss) * percent_depo)/100.0)/pips)/100000 ; }

Hi, i please need a code/ formula which resizes the lot size based on Account Risk % calculated by including the STOPLOSS, and taking in consideration that my account is in EUR.

What i have is this:

But this one doesnt consider the stoploss

So i found this one on google search

And this one

But none of this works, please help me fix them, or give me a better one, thanks!
