So this is not about a full Trading System discussion, rather a component of it.

FWIW I have an approach synthesised from Elder Triple Screen and others, and as said elsewhere I am not a short term player (Intermediate to Long term). That said I continue to try to learn and experiment to see if I can make money in shorter terms, but (honestly) for the most part my temperament is probably not suited to those time scales.

Here is a Weekly Chart that shows an open trade in my attempt to amplify what I have already written, which is not that complex.
