I am not a day-trader so I'm not able to guarantee this method intra-day but see what you think. It is aimed at exploiting trends to the maximum potential. It sacrifices unrealised early profit in favour of potential excess later gains while not entailing any additional capital risk.
Firstly, be aware this is a trend-following tactic. Once I have entered e.g. long in an uptrend I set a new buy order at the same distance above entry as the initial stop is below it, let's call that distance r (r for risk). The initial SL is TA-based. When the second trade is triggered, I move the SL on Trade 1 to b/e, Trade 2's SL is Trade 1's entry. Hopefully the uptrend continues and a series of new trades are triggered. When each new trade is opened, I set a new buy order r points above the last entry and move all SL's r points higher. So capital risk never increases beyond r.
After the initial trade plus 3 pyramid trades, you enter territory where your returns if all SL's are hit exceed those on a single trade bought and held, and these returns increase parabolically with each trade added.
Food for thought I hope.
