@hadees Thanks for your reply. Yes, I think your solution can work.

Dear all,

May I know in what case to use Trailing Pending Orders?

What is it difference from "slide order"?

If I want to develop a News EA which can create pending orders right before news. The EA can able to modify the pending order up and down based on current price until the news announcement. Should I use "Trailing Pending Order" or "Slide Order"?

Hope you can provide some example project as I can a very new user.

Thanks

Great work!

OK now. Found that it is MQL5 function for checking if the Expert Advisor is allowed to trade and trading context is not busy.

May I know what is the purpose of the function "IsTradeAllowed()"?

I cannot find logic of this function. Please kindly advise.
