And while we're (not?) on the subject ... I'll explain my interest in your system ...
A couple of years ago I came up with a system of 3, 13 and 39-period EMA's on 4-hour and/or 3-hour currency charts. Entry signals were 13/39 crossovers, filtered by various combinations of DMI/ADX (definitely the most promising) MACD (less useful) and RSI (ditto) using various different settings and criteria. Exits were mostly re-crossovers of the shorter 3-EMA. Initial stop-losses related to ATR and then trailed.
This system was "in the market" quite a bit more than yours (which was perhaps its problem, or one of them).
To cut a long story short, although initial back-testing and following it up looked extremely encouraging, I couldn't find a way to make it work consistently or reliably enough to trade it with real money, eventually stopped trying to tweak it and have since then acquired a greater interest in trading without indicators (as you might gather from my other posts around here). But a system like yours brings back mostly happy memories.
So I'm very interested.
