Help with order management logic

[imagineer]

I have written an order management algo for a simple MA crossover strategy. I have been backtesting it with 2 year of 1 min interval ES data. The main idea is to enter positions using stop limit orders, to exit positions using also stop limit orders and to use stop orders for stoploss. Line 187, 205 and 220 are for debug purpose. As you can see if you run the program, the if-block of line 204 never get executed. I have been scatching my head for almost a week. I really appreciate if anyone can shed some light on it.
P.S. the code is really simple to follow.
Thanks.

imagineer, please add TraceOrders = true to the Initialize(), you most likely run into the Internal Order Handling Rules with this and the script would not make it into OnExecution potentially - http://www.ninjatrader-support2.com/...ead.php?t=3627

NinjaTrader 7 offers new features in this regard offering more flexibility - http://www.ninjatrader.com/webnew/NT7/NinjaTrader7.html

New Unmanaged Order Submission
In 6.5 some users were burdened with our "Internal Order Handling" rules. We have introduced unmanaged order submission which bypasses the convenience of our order handling layer. This lower level of programming allows you to do what you want relative to order submission/management without any limitations other than any imposed by your broker. There are only three methods, SubmitOrder(), ChangeOrder() and CancelOrder(). You then get the flexibility of managing your orders how you see fit and optionally handling rejections.
