Thanks to GcNaif and Nmike for bringing my attention to this cloning technique.
Actually its not new for me, i have used it before succesfully but only by "instinct"
We know price action often likes cloning (wave cloning, patterns, duplication i often use, etc)
This techique is similar but very simple and useful.
Looking at chart on USDCAD price history we see the channel duplication worked perfectly before (sky-blue channel).
It still hurts me when i remember i was stopped out by a few pips before price going in my favor 800 pips (ARRGGGGHH!!!!!.....)
I remember very clear how difficult was to find an entry point then using another trading systems. This cloning technique would have been more useful and easy.
Im trying to use and test this technique now, we see the price is on clear but respecting the base channel, specially the middle points.
Very important: this technique must be used not alone but in confluence with another reasons/trading systems.
I expect some reaction near the levels shown on the chart. My prefered scenario is because i think the price needs a correction.
Lets see what happens.
