Conditional Stop Losses not filling

Hi guys,

I'm stumped - I execute the code attached, which aims to send out a bracket order, conditional on the original entry ticket being filled, but for some reason, the the child stop market / limit orders do not get filled despite price moving through them within any given day. The end of day scheduler catches the order and liquidates but the log shows no sign on any intermediate orders being filled, once the orignal entry gets laid. I've experiemented with moving the limit order / stop order inside the ‘OnData] thus trying to execute everything at once but I would have thought that the onOrderEvent approach would work. I fear that there is some kind of indentation error that is sneakily passing the compiler which I’m failing to see.  Any tips would be greatly appreciated. FYI: This is my first go at an algorithm so apologies for any sloppy code! Its an attempt at creating an hourly openingrange breakout using the rolling window etc.
