I am new to MQL4 programming, but have programmed in other languages. After learning the language over the last few months, I have written an EA with trailing stop. In Strategy Tester it works fine, but does not get activated on VPS. (My Internet connection quality is not good, so I rented a VPS for a month for trial purpose.) After moving my EA to a VPS, I have been watching on my local terminal, and have found that trailing stop does not get activated at all, even after the trade is profitable in both BUY and SELL cases . To test it, I have kept T railing Stop at a low value of 25 points. I have copied the code below, which I got from this forum. Any help will be really appreciated. I am using a 5-digit ECN broker for my trading.

 

What was the error in the log ?

The code is incomplete.

What was the error in the log ?

The code is incomplete.

Thanks much, Marco, for your help. I posted the code only for the Trailing Stop part. Here is the complete code for the EA. There was no error in the log. In fact, the log shows that no modification to any order was ever made in the VPS expert journal.

 

Your problem is here

int count = 0;

This value doesnt change and as a result of that

for (i = count; i > 0; i--)

i is never > 0

 

Use this for youy loop


for (int i = OrdersTotal() - 1; i >= 0; i--)
{
 //
}
 
Marco vd Heijden:

i is never > 0


Marco, I cannot thank you enough for pinpointing the problem and helping me out. I did run a little debugging process by inserting "Alert("count1=", count);" just after the "for (int i = 0; i < total; i++) { //}" loop. The log entries show that value of count does change after an order is placed. However, the "for (int i = count; i > 0; i--) {//}" loop never gets executed. It gives me a starting point to work on the problem. So, much appreciated.

 
Mostafa Moujezi Zarandi:

Thanks much, Mostafa, for helping me out. I do have a question, though. If OrdersTotal()=1, then if I start "for (int i = OrdersTotal()-1; i >= 0; i--) {//}" loop, it will not get executed because i=OrdersTotal()-1=1-1=0. Should not I start this for-loop at i=OrdersTotal() instead?

 
ryan smith: If OrdersTotal()=1, then if I start "for (int i = OrdersTotal()-1; i >= 0; i--) {//}" loop, it will not get executed because i=OrdersTotal()-1=1-1=0. Should not I start this for-loop at i=OrdersTotal() instead?

I equals zero and therefor "i >= 0" is true.

Thanks much, William. You are absolutely right! I forgot about ">". Much appreciated.
