Hello BlackCode!
1 - Yes, ILQ is NFA regulated. The FIFO and Hedging rules are enforced in the back-office trading account. It's called 'netting'. The Metatrader 4 software is used as a 'gateway' to the account and has full trading functionality, while allowing us to be FIFO and Hedging compliant.
2 - The results DEFINITELY vary from account-to-account, but they usually move in the same direction. Not sure why the variance yet. We saw differences between accounts from Day #1 so it isn't related to liquidity or the number of accounts trading it. I think it just depends on the exact ticks received by each platform.
Our introducing broker and myself are currently working with ILQ to discover the reasons for the slippage and get it reduced. Slippage was no issue in August and got worse in September.
3 - We continued to trade 1.1.6 while testing 1.2.0. The main difference is that 1.2.0 doesn't trade after gaps, and that's fine, but I wanted to run it for a week or two to make sure it was stable and didn't have 'other issues' before running it on large live accounts. We'll be updating to 1.2.0 this week.
Thanks for the questions!
