I have designed a day trading system for HS indices. On paper it looks good. I have found a major problem between paper trading and actual trading. While during paper trading, I was happy to hold over lunch break. I found it very difficult to hold a position open - due to the volatility of HS while trading for real. The lunch time gap can be quite substantial - one of the recent one at over 800 points on 20th Nov. This could easily jump over my preset stop loss. Any suggestions? Thanks
