The week's question
In March 2025, in the thread "Re: OT, out", Umm asked the members: "Do you think it is because America is made up of magical soil that makes businesses based in America magically profitable?" This week it is put to everyone again. The button below opens the small thread re-asking it - read what others have said so far, then give your own answer as an ordinary reply.

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.
