And a lot of practice as one must hone their techniques.In real time in the thick of the battle, it is easy to be wrong, out of sync, e.g. sell @09:35 and SL at a loss? Maybe a wider SL but then I could end up with bigger cum loss at the end of the day?
It comes down to experience and technique.
I wouldn't sell at bar 9:35 because at that point we had.... what?
1)gap opening
2) bears failed to reverse and trends strongly up.
3) At bar 9:35 it is just a PB and profit taking at that point. We don't yet know if it is going into a range but there are some indications in may. Why? 2 legs up. Best to wait after profit taking and see if it continues up off the PB or morphs into a range.
4) However, if I did short bar 9:35 my stoploss has to be at min above high of bar 9:30 and if by chance I got taken out on that SL I would assume it is probably going up for at least a small third leg and I would double up long my previous short size. That puts the odds back in my favor of getting at least my loss back in short order and maybe print money.
The overall context is an opening spike (gap leg #1.), A PB (bars 8:30 - bars 9:00) then a continuation of the bullish spike. At this point it is for all practical purpose ....a channel. Leg 2 is made in that channel. Remember the market cycle. Trend ( BO...spike...etc), first PB then resumption (leg#2) becomes a channel. Channels usually start to flatten out and price goes into a TR or a several bar pause for profit taking. bars 9:05 thru bars 9:50. If keeps going sideway after that then it is likely going into a TR. Once price after those PB bars 30, 35, and 40 continue sideways for 20 bars counting from left (see my box) then we are no longer in a PB but a TR and that is when I use TR techniques. Sometimes I will fudge a little that and start before 20 bars if I think it is just going to keep going sideways.
