Just a screenshot of backtest results of the "reverse-method", which has largely been borne out by forward testing - 'largely' 'cos the version I forward-test has different 'greedier' settings! The PF is unspectacular, as is the equity curve - roughly 80% p.a. return though - but at least it points in the right direction

What is interesting is the drawdown however, especially for a martingaler! Moreover, 'restrictions' imposed make it virtually impossible to blow a reasonably sized account!! ($10,000) btw, this covers from Sept '06 -> present - the only period that is worth a damn as far as backtesting results are concerned (imo), and it only seem to produce viable results with USDJPY...
Minime, excuse this brief interruption in thread-flow but I've had time on my hands (scary market today

) - back to your original idea!
