Subject: Re: Timing period examined, 200 vs 325 days
The sell signal is clear but for the buy signal it appears that there are 3 possibilities:

- Buy when the index closes above the moving average, regardless of the GTT signal.
- Even if the index closes above the MA, only buy once the GTT signal also turns positive.
- Buy when the GTT signal turns positive, even if the index is still below the MA.

I think you have covered 2 of the 3.
