I hope it is not the case for his sake, but perhaps he no longer comes here because the maths have caught up with him and he is no longer a winner.

The fact is, if the only way you can profit is by stopping at a certain target, it means your method has no edge.

On the other hand, he may have a very profitable edge and is severely cutting his profits by stopping, which will threaten his long-term edge.

Either way, it is not a good position to be in and certainly not a method to be used.
