Green and Red Triangles tell the overall trend buy/sell are pretty obvious, what they do
the way i use it is: long (buy) 50% of your position size when we have buy and then long (buy) another 50% when i get the green triangle short (sell) 50% of your position size when we have sell and then short (sell) another 50% when i get the red triangle
also, i look at my RSI indicator to confirm the entry and exits RSI is above green line and indicator says buy, it's a safe long RSI is below green line and indicator says sell, it's a safe short
won't be able to describe much as the more you use it, more you get used to it cheers!
