OrderSend works on market, but not in backtests 134 error

[baku85]

Hi,

 I have some strange issue while using backtester.

Here is some code sample:

 

double ND(double val)
  {
   return(NormalizeDouble(val, Digits));
  }

void OnTick()
  {
   double price=Ask;
   double minstoplevel = MarketInfo(Symbol(),MODE_STOPLEVEL)+10;
   double stoploss=ND(Ask+minstoplevel*Point);
   double takeprofit=ND(Ask-minstoplevel*3*Point);
   OrderSend(Symbol(),OP_SELL,0.01, Bid,10,0,0,"My order",16384,0,clrGreen);  
  }

 when I add this strategy to market, on each tick new order is coming.

But while running backtests I have errors:

can anyone tell me why is that ?

 

Thanks !

You have to check that there is enough free margin to trade your selected volume before sending an order.

Read the documentation, please.

What do you expect if opening a new order every tick?

ok thanks :) working code:

 

if (AccountFreeMarginCheck(Symbol(), OP_SELL, 0.01) > 0) {
      OrderSend(Symbol(),OP_SELL,0.01, Bid,10,0,0,"My order",16384,0,clrGreen);  
   }

Jose Francisco Casado Fernandez: You have to check that there is enough free margin to trade your selected volume before sending an order.

Which is sufficient to open but not prevent stop out. You place the stop where it needs to be - where the reason for the trade is no longer valid. E.g. trading a support bounce the stop goes below the support. Account Balance * percent/100 = RISK = OrderLots * (|OrderOpenPrice - OrderStopLoss| * DeltaPerLot + CommissionPerLot) (Note OOP-OSL includes the SPREAD, and DeltaPerLot is usually around $10/pip but it takes account of the exchange rates of the pair vs. your account currency.) Do NOT use TickValue by itself - DeltaPerLot You must normalize lots properly and check against min and max. You must also check FreeMargin to avoid stop out

Thanks ! 

I would say you need to add more logic to your ordering.

Here is what I do to keep from getting killed by Margin Calls:

double MarginFree =  AccountInfoDouble(ACCOUNT_MARGIN_FREE);

double EQTY =  AccountInfoDouble(ACCOUNT_EQUITY);

double MarginCheck = (MarginFree/EQTY);

if(SomeOrderRule && MarginCheck > 0.30) { //Make sure you have more than 30% margin left before ordering (This can be adjusted depending on your comfort level)

      if(OrderCount < 6)

           OrderSend(Symbol(),OP_BUY,.10,Ask,3,0,Ask+.025,NULL,NULL,0,clrTeal); }

	Which is sufficient to open but not prevent stop out.

You can't ever prevent a StopOut.

• 1. Your formula "DeltaPerLot" is variable (TickValue is variable, it changes with the prices movements). Therefore even if you calculate it at the moment of your entry, it doesn't assure that you are save from a StopOut later.
• 2. You also may open other positions later (manual or with other EA's) which would affect your Margin.
• 3. You also may change your Stop Loss later, or not to use a Stop Loss, and close your position with anyother rule (an opposite signal, for example).
• 4. There may be a price gap that causes your Stop Loss not to trigger where you placed it.

It is why I consider it is useless to calculate that at the moment of your entry if your aim is only prevent a StopOut. I think that's only useful if your aim is to get a ROUGH IDEA of what you can lose in that trade, but it will not prevent a Stop Out.

You're going to get a zero-divide error if this code runs before your terminal has connected e.g. restart.
