i would not suggest a complete bar formation
if using 5 min chart wait a little check for volume if it is good the probably u r right other solution may be let the bar complete and put a limit order at level just some small points or ticks above or below di+,di- cut level as u think .
di+ di- cut in five min time frame could be considered as a good signal and if even u lose and it signals again take that position u will win for sure .
better paper trade this strategy per day for at least 1 week
i m using it per day and has already converted my 980 in to 605679 rupese in 3 months i also not obeyed the rules strictly or so called used my mind so my results do not match with the data posted above probably .
happy trading
