I can't understand the logic of the compiler. I have a function. I declare an external variable.
int start;
further the function body
double B()
{
int i=0, k=OrdersHistoryTotal();
for (i=k-1; i<=k; i++) {
if (OrderSelect(i, SELECT_BY_POS, MODE_HISTORY)!=false) {
if(OrderType()==OP_SELL) {
if(OrderProfit()< 0) {start=1;}
}
}
}
}
The value of the start variable must be memorized and equated with zero when needed. But in this case, if OrderProfit()<0 , then start=1, and if OrderProfit()> 0 , then automatically start=0.
no
if OrderProfit()> 0, the variable will store the same value
Can you tell me where to find it? It's all in English.
no
If OrderProfit()> 0, what was in the variable remains
Here is the function .

Hi, can you tell me how to change orders OP_ BUYSTOP and OP_SELLSTOP in my EA for OP_SELLLIMIT and OP_BUYLIMIT? I tried it and my BUYLIMIT orders are placed, but SELLLIMIT ones don't even think so, maybe I'm doing something wrong?

Hello friends, can you please help me with this problem?
I'm writing an Expert Advisor with software stoploss, the basic scheme of algorithm is as follows:
int start()
{double x, PreProfit, TekProfit;
for (x=0; x<1; x++) //The For loop operator (in theory) should be executed 1 time
{PreviousProfit=(-20);}// Assign 1 time value (in theory)!
TextProfit=OrderProfit();//find the profit of the selected order
if (PredPreviousProfit<TekProfit)//if the current profit is higher than the previous one, then...
{WeakProfit=TekProfit;}// Assign the PredCompetitive variable a new value!
//then the PredCompanyProfit variable should hold the highest profit value of all time!
}
The catch is that the value of the variable "x" is reset to zero with a new tick and the value (-20) is assigned to the "PredPreCompetition" variable with every new tick! Thus, the entire sense of the algorithm is lost! The "PrevPreprofit" variable has been designed to constantly keep the maximal value of the order profit until it is forced to "dump" this value when the order is closed.
What is the mistake? Maybe there are other solutions for this problem? I am very grateful in advance!

Didn't you forget about Bid and Ask when you changed it?
Who knows how to make a standard indicator visible in the strategy tester?
