Hi, can anyone tell me why the following is happening? It is playing havoc with my EA.

I have a position open for some time. Without my intervention, it is closed and replaced with a new position. The original (now closed) position has "to # (then the new ticket number)" posted in its Comment field. The new (replacement) position has "from # (then the old ticket number)" posted in its Comment field. The opening price of the replacement position is identical to the closing price of the original position.

My EA depends upon retaining the original ticket number, so you can imagine how frustrating this is...

Any help much appreciated.
Thanks
