Waiting till Target 2 around 550's zone or booking profits at 537's zone is completely dependent on your trade plan. This is harmonic setup, if you are not well-versed try other setups,which are applicable here, you can take trade based on that, but it should be in your trade plan. I think people hate this line the most which I repeat in every post :) Its for your benefits n profit, I'm not gonna gain anything if you follow your plan n trade with discipline !
