Dear OZFX and other readers of this thread
Firstly I would like to congratulate OZFX on a great system. I have undertaken some rather crude backtesting for 2007 and 2008 and have found some interesting results. I am not going to publish them here but I will say that my two criteria for a good system both appear to be fulfilled. These are:
* Average win > average loss
* Probability of win > probability of loss.
The first condition seems to (just about) be satisfied, but where the system really does well is the second condition; it appears to be in the 75%+ category which is simply fantastic.
One thing I would mention is that your pip counting method is a little dodgy. If you want to count pips in a way that sums together the winners, you also have to sum together the losers! This means that if a winner is 50 + 100 + 150 + 200 + 250 = 750 pips, then a loser is 100*5 = 500 pips.
Alternatively you can just call a loser 100 pips and the winner in the example above is 750/5 = 150
Anyway, such matters may be considered as somewhat trivial and you have certainly done well in the development of the system.
I am currently investigating some of the money management rules. I am starting to think that it may be better off as follows.
Lot 1: TakeProfit = 100
Lot 2: TakeProfit = 150
Lot 3: TakeProfit = 200
Lot 4: TakeProfit = 250
Lot 5: Let run
But with the following stop procedure:
Initial stop: on/around 100
When Profit = 50, stop moves to BE
When Profit = 150, stop moves to 50
And then trail it by 100 from each 50 increment
I think that the trailing stop does generally produce better results as long as it is not trailed more aggressively than 100 pips.
For me, this system seems to have real potential. The next steps for me are going to be:
*To look into expressing the stops and TPs as a function of the ATR in order to adapt to different pairs.
*To find the optimal money management system
*To investigate a few different filters (do they add value or not? and which perform the best?)
So a huge thank you from me for being so generous with your time and ideas. I am sure that you have helped a great many people and continue to do so with your blog updates.
Anyway, enough from me
Cheers
