Adam, I haven't combed through the recent posts, are you live on a system yet?
You mention a system that looked good in testing then "blew up badly".. this is exactly what I mean. You have to suck it up through the drawdown and trust in the positive expectancy.. this is the hard part, believe me.
I keep forgetting I called the journal 'deadline june'. Take it as an artifact of the T2W journal implementation.
I should have just called it 'The Adamus Journal'.
It did serve a very useful purpose in helping me to get my show on the road. Admittedly my show is not on the road, but I'm at a stage where I can't really improve my working approach anymore by heaping a sense of time pressure on myself. I used to waste days (even years) on irrelevancies. Now my time is wasted just by technical issues and I have learnt to prioritize and focus much better.
As for when I reckon I will get the show on the road, I don't know. Next week probably. It all depends on how that "positive expectancy" is looking.
I'm going to try posting some results here from backtesting the same trading system on different data:

I expect that table will have the format scrambled by trade2win but hopefully it shows the differences.
This is 10 pairs on one year of data of 1 minute bars using my version of the 3Ducks system.
IB and FXCM data give pretty much the same sort of results surprisingly. Often FXCM data is just as different from IB as DTC.
This helped me appreciate what I'd known theoretically for a long time but hadn't internalised, that backtesting results are nothing. I just hope that the systems that backtested and then forward test profitably also turn a profit in real time.
NB NinjaTrader spits out the average of the max drawdown for the basket - not the max max drawdown.
This system is good, because it wins on all three data, but I have some systems which looked great on one data but were just miserable on the other sets.
I guess the message here is that it's good to have two sources of data to backtest on.
Are you completely comfortable with the mechanical side of things, i.e. order proccessing, trade management etc., it's just the actual trading rules you need to sort out?
