I believe in ta. When I connect two lowest points on a chart with a ray and the ray is touched in the future I am buying/selling bounces. You can see a great example for example here: https://sola.ai/posts/MjViOGM/
I don't think this is my final strategy but I believe a strategy should be simple.
I think I shouldn't trade exotic pairs. They always broke my stop-losses. 😂
