A very simple system which made great results.
1. Just before 8:00 am gmt, look back at the last 4 hour periods. Write down the high and low inside these periods for GBPUSD
2. If High-Low <= 40 pips then put two orders: BUY at high+5 pips, SELL at Low-5 pips. SL should be the opposite orders. i.e. the sell price should be the SL for the BUY order, and vice versa
3. Place TP at +100 pips.
4. If High-Low is 41 or more do not trade that day.
5. close all orders and pending orders at 6:00 pm gmt.
6. If one order is triggered, then keep the other sitting just there.
7. Once you are +30 pips in profit move SL to break even.
8. Once you are +40, place SL at +10, and so on
Happy Trading
