#property strict
Take a look at some of your return(), most don't return a value.
what bool is return(false)?
you haven't returned a value.
Doesn't this cause an error?

Thank you for your response GrumpyDuckMan. I am actually not versed in mql4 coding (ie. I am a complete novice) and this EA was not written by me. As the EA stands, it does work and causes no errors. However, like already explained, it just opens pending orders for a pair only after a previous order for that pair has been closed. I, however, want it to open pending orders irrespective of their already being open orders. Thanks
Hello again GrumpyDuckMan. I copied and pasted the code as your instructed,
but got the following errors after I compiled it:

GrumpyDuckMan, I thank you for your assistance and I am most grateful. I have compiled and run you code above. Unfortunately, it does not do what I want either. That is to to continue to place pending orders at the next round numbers above and below the price as the price moves irrespective of there being open trades that have not been closed. Thanks
Hello GrumpyDuckMan. Thank you for your response. The code works as it is currently. All I was just after was the amendment I have repeatedly mentioned - continue to open pending orders (buy stop above and sell stop below current price at round numbers) even if there are already open orders yet to be closed for the pair. Thanks
Hello again,
you have almost identified one of your problems. Please try what I asked you to do. you will be a little surprised as to what the code is actually doing. Just add variables to watch windows in debug mode and use F11 to step through it.
I can tell you right now your code below will not work.
bool Do_Trades(double B_Price,double S_Price)
{
Lots=NormalizeDouble(Fixed_Lots,LotDigits);
if(Use_MM)Lots=NormalizeDouble(Get_Lots(),LotDigits);
int
result=0;
Buy_SL=NormalizeDouble(B_Price-StopLoss,Digits);
Sell_SL= NormalizeDouble(S_Price+StopLoss,Digits);
Buy_TP = NormalizeDouble(B_Price + TakeProfit,Digits);
Sell_TP=NormalizeDouble(S_Price - TakeProfit,Digits);
B_Ticket=OrderSend(Symbol(),OP_BUYSTOP,Lots,B_Price,30,Buy_SL,Buy_TP,Order_Cmt,MagicNumber,0,CLR_NONE);
if(B_Ticket<0)Alert("Buy ordersend error - error = "+GetLastError());
if(B_Ticket>0)result++;
S_Ticket=OrderSend(Symbol(),OP_SELLSTOP,Lots,S_Price,30,Sell_SL,Sell_TP,Order_Cmt,MagicNumber,0,CLR_NONE);
if(S_Ticket<0)Alert("Sell ordersend error - error = "+GetLastError());
if(S_Ticket>0)result++;
if(result==2)return(true);
Pending_Delete();
return(false);
}
Hello GrumpyDuckMan, once again thanks for your assistance. Just to re-iterate, I am not a coder and don't know much at all about mql4 coding. I did not write the original code and really do not have much idea what each line of code does or mean. Following your suggestions will just lead to me coming back asking more and more questions. If you are able to amend the code to do what I want it to do, then I will be most grateful. If not, then thanks for your assistance anyway.

I would be most grateful if somebody could amend (or advise me what to amend) the EA below for me please. Its is a simple EA that opens a pending buy stop and sell stop at round numbers (every 100 pips in this case). The issue I have with it is that when price moves towards to next round number, the EA does not place any more pending orders (buy stops and sell stops) unless the first trades have been closed (target hit, stop loss hit or cancelled). I would like it to continue to pending orders as price moves to the next round number irrespective of whether there are already open trades at the previous round number. The main code of the EA is copied below. Many thanks!
