I am getting error 1 a good percentage of the time when modifying the stop loss on existing orders. When looking at the openprice, current stoploss and the proposed stoploss it looks ok.

For example, on a EURUSDm short trade (after checking the conditons are valid) I use ASK + 0.0025 for the new stoploss so thought the distance from the BID price would be sufficient in most cases.

My question are;

1. My EA display says its ok but it fails - could this be due to the rounding of the 5th decomal place. In other words is the 5th decimal place significant when setting the stoploss. requiring normalise double all the time?

If so should MT4 be changed to do this automatically??

2. I have checked the spread with Error 1 and its ok at about 185 but the stop and freeze levels are both 05. Assume this is 0.00005, but how do i use these figures. I know they can prevent a trade modification, but how can i determine if the trade will be accepted or rejected - how exactly do I use these levels

Did you look at what error 1 means ?

"OrderModify attempts to replace the values already set with the same values. One or more values must be changed, then modification attempt can be repeated."

Here. sxTed code gives a good list of things to check for to avoid Error#1. We cannot say whats wrong with your code because we cannot see it.
