I don't usually take impulse entries but I have taken a similar setup on GJ 3 times before already this week and they were all winning trades
Entry was taken at the point we broke below the wick of the bearish 30m candle on support anticipating price to come down to the next support. I used my usual 2% risk and price very quickly moved towards target TP hit and I secured 3.2% account increase
If we flipped bullish I would have managed risk by closing half of my positions so that if SL hit I lost less than I was happy to lose.
