You can use the scripts for MT4/MT5 for example to be downloaded from CodeBase.
Use search here - this link - or if you do not find anything (I know that there are few scripts on CodeBase related to what you explaned) so order the script in Freelance (I think - it will not be expensive).
Contacts and requests
Hi everybody!
I would kindly ask you for your help. I opened a pending order in Meta Trader 4, but I would like to open 5 exactly the same pending orders (sell limit). Is there any chance that I just copy-paste it inside Meta Trader?
Thank you for your kind reply.
