The system has done surprisingly well after one week of trading. One issue I ran into was this weekend when the platform shut down. Upon opening again, the strategy trader platform shows that the previous open positions no longer match. I turned on the grid strategy regardless and I believe it is now doubling up on the trades. So in effect, the lot size has increased from 10k to 20k. I'll have to investigate this a little more, but the strategy is still the same, simply a larger lot size.
