I can put some round sample figures in this to make it more plain.
Suppose you buy into an uptrend with £1 per point at 10,000 and put in a 100pt trailing stop-loss. Initial risk is £100. If price goes to 10,500 and then falls back to 10,400 the SL is triggered and you gain 400pts, for £400.
To increase this return, you could go in at say £2/pt, but then your initial risk would be doubled to £200. I'm assuming you have to set your initial SL at 9,900 based on the TA.
My suggestion is to set a new buy at 10,100 as soon as the initial position is opened. Give this also a 100pt SL. When the 10,100 long is triggered, move the SL on the initial trade to b/e, 10,000. Set a new buy order at 10,200, also with a 100pt SL. And keep doing this: add a new trade every 100pts and move all the SL's of the earlier trades up 100pts when it triggers.
Now, when price has risen to 10,500, you will have 6 parallel trades open. If price falls back to 10,400, all the SL's will be triggered, and gain will be £900 instead of £400, at no additional risk to your capital. This is an improvement of 125% over the standard gain from a single long in the same scenario. Of course, as you add further pyramid trades, the % improvement accelerates. As a demonstration, at the (admittedly unlikely) total of 20 trades, a single long would gain £1,800: the pyramid series would deliver £17,000!
