Hi,

Can somebody explain to me what the following block of MQL4 code means and what it does in an expert?

datetime timeprev=0;
//---------------------
if(timeprev==Time[0])
return(0);
timeprev=Time[0];

Thanks.

instead of working every tick like most do, this will cause it to only work on a new candle.

Isn't the code reinitializing the time every tick anyway?

what happens is when the new candle is formed Time[0] is no longer the same as time previous. when that happens the code falls through and the time previous is set to the current candles time and any code after it is executed. Next tick through it will see that the time previous is still equal to the current time and a return is executed.

Thanks magnumfreak for your answer.

Does this code block reduce the quality of EA test results in MetaTrader strategy tester? I noticed that when I test without this code the test takes longer and the profit is much lower.

And in live trading (if I am using H4 time frame and basing my strategy signals on closed candles (bar 1 & 2) ) will it effect the results?

it forces the EA to only make adjustments (i.e move stops) at the close of a candle. To me, this is a much better method of moving stops as it will help prevent movement too soon. I don't think it impacts the quality of the backtest results, it just provides different results.

Thanks again.

You will get the most effective help if you post all of your code since the way these code snippets act is highly dependent on where they are in the code
