EA open trade on open price

[ezraluandre]

Hi I tired to open trade on the next bar by using the code from earnforex web. After using this code I use this code to open the trade,

slippage = 0;
if(logic == 1)
   {
        OpenCandle = iOpen(Symbol(),PERIOD_CURRENT,0);
        double openPriceBuy    = OpenCandle;
        double stoplossBuy     = OpenCandle - stoploss;
        double takeProfitBuy   = OpenCandle + takeprofit;
        double lotsizeBuy      = 0.01;
        int    ticket          = OrderSend(Symbol(),OP_BUY,lotSizeBuy,openPriceBuy,slippage,stoplossBuy,takeProfitBuy,"BUY",MagicNumber);
   }
 
if(logic == 2)
   {
        OpenCandle = iOpen(Symbol(),PERIOD_CURRENT,0);
        double openPriceSell    = OpenCandle;
        double stoplossSell     = OpenCandle - stoploss;
        double takeProfitSell   = OpenCandle + takeprofit;
        double lotsizeSell      = 0.01;
        int    ticket          = OrderSend(Symbol(),OP_BUY,lotSizeSell,openPriceSell,slippage,stoplossSell,takeProfitSell,"BUY",MagicNumber);
   }

But when I backtested my strategy I found that EA will open trade on next candle but on the close price or near close price (pic attached, logic where dot occur). Anyone can tell why EA open trade near close price instead of open price?

Where do you check for a new bar? The code that you inserted doesn't check for a new bar.

Sorry my bad, my code that I posted is nested on IsNewCandle() function.

It is hard to say anything without seeing the entire code involved.

I attached the simple EA that I working on. This problem occurred not only using this strategy, even a simple moving average crossover has the same problem.

CustomFunction.mqh appears to be missing and it isn't clear how you define IsNewCandle().

IsNewCandle () is from this page https://www.earnforex.com/guides/mql4-on-new-bar/

It is quite important to see how it is used exactly.

Here I upload the mql4 file with every custom function needed

I don't know. I've just run it on Daily and it took entries only at the beginning of a bar:


The only thing I changed is replacing the calls to custom indicators with random signals.

It doesn't have a problem with the time of trades open. It has problem with the entry price of the open trades.

When new candle form the price of open, high, close and low would be the same. When we send OrderSend() of short, the bid price should be the open price of that candle, but in my screen capture the entry price of the order is close price or near it.

my question is does using IsNewCandle() function in https://www.earnforex.com/guides/mql4-on-new-bar/ doesn't make entry price of short order a open price of a candle?

As you can see on the attached screenshot, it does enter exactly at the Open prices:


If it doesn't in your case, then you have to check what price Model you use in the backtest and the quality of the ticks that your platform generates to use for trading.
