Bug: Forex Lot Sizes

[reach4thelasers]

Ninjatrader accepts invalid Forex lot sizes, which are not detected until the order is triggered and the bracket orders are submitted to FXCM at which point they are rejected. This leaves Ninjatrader with an exposed open position without stop-loss or limit orders.

Steps to reproduce:

1. Start a new custom ATM Strategy.
2. Position size: 3000
3. Target 1: 1500, Stop:10 pip, target 20 pip
4. Target 2: 1500, Stop: 10 pip, target 40 pip
5. Place order
6. Go to bed
7. Wake up the next day to find your account is empty following an unexpected currency flash-crash

(joking aside - a market order will illustrate the issue)

Solution: Ninjatrader should accept quantities in Micro Lots (x1000), not in individual units of currency. (See a screenshot of FXCM's order dialog). Furthermore if errors occur when submitting stop-loss and target orders, the position should immediately be closed!!!!!!!!!

This is serious professional incompetence. Did you guys do any user acceptance testing with actual Forex Traders when you were developing NT8?

Thanks for the feedback.

I will submit two feature requests:

• Put logic in place to prevent invalid lot sizes
• Add an option that will flatten positions and cancel orders when a order rejection occurs

This behavior is currently expected and behaves the same as NinjaTrader 7 in this scenario. Many of the features and enhancements put in place come from feedback by users such as yourself. We'll take this into consideration.
