Much obliged @haejin
From gambling's stand point of view, if you gave us potential of the next wave and the probability of it happening, we could calculate "pot odds" and equity as poker players call it.
But that would be too easy for us woudn't it :)
You can do it. It's called risk vs reward ratio. Depend of your stop loss and take profit levels. It's more for day/swing trading because haejin is focused on hedge trading, he buy and hold, sometimes take profit, sometimes buy more, but if it does not goes his way, he just hodl :-)
See @philakonecrypto (account closed) or philakone on youtube, he has made really good tutorials for day trading.
