Good afternoon, Can anyone suggest a solution to this issue. There is a code with entry on M15, but the signal from H1 is taken into account. While there is a signal on H1, on M15 the indicator gives several signals. The question is how to limit it to one (i.e. the first signal).
k=0;
for (i=OrdersTotal()-1;i>=0;i--)
{
RefreshRates();
if(OrderSelect (i, SELECT_BY_POS, MODE_TRADES) == true) a = 0;
if (OrderSymbol() == Symbol() && OrderMagicNumber() == Magic) k++;
}
if( stM1 >= 80 && stM0 < 80 && stH0 < 30 && k==0 && opp != Time[0]) // sale

Everything works, displays the information correctly, but as soon as you restart the terminal, the panel stops working (writes that the balance is 0 and the rest of the information stops updating and freezes on one position, simply hangs up). How to combat this?

I'm attaching a screenshot:Similar problem discussed not so long ago, have you looked at the log or expert tab, I can say with 100% certainty that you have a division by zero error in these lines
ObjectSetText("Max DD","Max DD: "+DoubleToString (MaxDD,2)+" ("+DoubleToString((MaxDD*100)/AccountBalance(),2)+"%)",10,"Arial",PanelTextColor);

I wrote a small info panel:
{
//Расчет максимальной просадки
if (AccountProfit()<0)
{
if (AccountProfit()<MaxDD)
MaxDD=AccountProfit();
}
ObjectSetText("Balance","Balance: "+DoubleToString (AccountBalance(),2)+" "+AccountCurrency(),10,"Arial",PanelTextColor);
...
ObjectSetText("Leverage","Leverage: 1:"+IntegerToString(AccountLeverage(), 0),10,"Arial",PanelTextColor);
}
Everything works, displays the information correctly, but as soon as you restart the terminal, the panel stops working (writes that the balance is 0 and the rest of the information stops updating and freezes on one position, simply hangs up). How to struggle with it?
Screenshot attached:Try it like this:
{
if (AccountBalance()<5) return; // <<< if (AccountBalance()==0) return;
//Расчет максимальной просадки
if (AccountProfit()<0)
{
if (AccountProfit()<MaxDD)
MaxDD=AccountProfit();
}
ObjectSetText("Balance","Balance: "+DoubleToString (AccountBalance(),2)+" "+AccountCurrency(),10,"Arial",PanelTextColor);
...
ObjectSetText("Leverage","Leverage: 1:"+IntegerToString(AccountLeverage(), 0),10,"Arial",PanelTextColor);

Screenshot attached:I did a little magic on your panel. I got this code, I eliminated the error of division by zero .
