Does minimum position size in ProOrder differ from what it says on the manual trading ticket?
I had 3 systems stopped last night, 2 Dow, 1 DAX all with position size < €1, can’t see any other reason for them not to run.
I also had problem with some DAX systems this night. I think that is due to the high volatility of the markets in this week opening, also because they worked good in the last 3 weeks.
Maybe that’s it then. It’s the first time I’d run anything at less than €1 per point so I thought that might be the problem. Others that did take trades were all above 1.
