in jist: positional if i exit i am always on the lookout to reenter provided that i know the levels and they matched price action as well as volume the first time.
momentum trades : i dont generally type them here as by the time i type or punch whichver is earlier high chance that the entry /exit shall be missed which might lead to dejection and ultimately loss or small profit.
also momentum means you ride short distance with heavier load , so better if that stays the way it is.
intraday: either the sl gets triggered or trail gets triggered or trgt 1 trgt 2 are areas of profit booking
all said nd done trgts and sls are not written on stone but sand, so as one as i have sense that the trade is under duress i would look to find an exit from it.
all said if i manage to share 2to 3 decent trades a day as well as one option trade , i think thats good enough for a calm and attentive trader to make at the min 3to 5 k a day , a beginner in derivatives if he is managing to keep eachand every day mtm green that initself is an achivement , i have learnt it the hard way so i pen these points down so that it might help somebodys learning curve.
except for momnetum trades on which include scalping of 20 to 50 points on nifty and bnifty and even when the probability of trade being successful is higher than 50 percent i share it .
sl triggers are part of the game just as trgts are.
