fixing JPY_ID
Damn. Despite being drunk, I can't sleep, so I'll do another one of those systems to be fixed.
It would seem a typical case of overoptimization and curve fitting.

What does this system do? When there's a high daily range and markets are overbought and we're going down (moving average detects this) at a given time of the day we go short.
First of all I don't like about this system the fact that it only goes short. The performance in the sample used is excellent, and the it goes awry.
Good. If it turn it into a long system, it works as well, even though not as well.
Now i need to increase the range daily range filter or add an extra filter. Let's hide the out-of-sample for a moment.
Awesome. I have added an overstretched ingredient. If the market at that time is ovestretched and reversing, then i take the signal, otherwise I don't.
This is the worst fixing I've ever done.

Drawdown decreases and gets to reasonable levels, but profit gets cut by half. However this had to be done, because that system had obviously failed and a short-only system was unhealthy to begin with.
Four systems to go.
