Quah, enough of this "let's not think about things so much and just let me post the results" attitude -- that is the one factor for which I am sure is NOT helping anyone's trading
Very high probability?? I disagree. I would more comfortable saying to that it's a slight possibility. And until it occurs, and until the system can be foward tested real time, for a good period of time, and until the trader can look back over a reasonable period of time and ponder the success rate, and how much $$ they've made or lost, until all of that occurs, you can't fairly assert the probability of that kind of combined contract grand failure with any degree of accuracy.
And backtesting for it won't be accurate, as previously highlighted by many - not only because you accurately determine whether you would have been filled or not, but also because of this:
If you are trading off the 2 minute stochastics signal, then backtesting only shows the closing value of the signal at an even 2 minute intervals. But where would the the signal have been at the time of the odd-minute trades? (which by the way, make up a NOT insignificant proportion of 8 out of 11 trades) The signal could easily have you one way at the time the odd-minute trades are initiated, and another way when you backtest off the closing 2 minute value of the signal.
Illiquid asks "What's going to happen when 3 contracts get stopped out, reversed and stopped out again.....will you quickly dismiss the system ... ".
Well, obviously if you were following the system with the discipline that overall success demands of you, Quah's system will leave you down for the day. But does that really justify abandoning the system? If one is going to succeed at daytrading, one must expect down days. Anyone abandoning a system like this, which is proving successful realtime, simply because of a bad day or two per month is, frankly, searching for something that they'll never find (100% accuracy) All I am looking for is overall profitibility on a consistent basis. As long as at the end of the month, I'm ahead a sufficiently respectable amount then it doesn't bother me that 1 or 2 days a month I can expect to have 3 contracts stop me out twice in a row, leaving me with a down day.

Enough of the critical posting. I gotta say, illiquid, I find many of your comments argumentative and unreasonably critical and personal. Why do you do that? Surely we can discuss this thing reasonably.
