It's based on placing Buy Stop and Sell Stop pending orders at the distance that is easily calculated and depends on the volatility on the previous day. The recommended currency pairs are EURUSD, GBPUSD, USDJPY, AUDUSD, USDCAD, and NZDUSD.
The Buy Stop pending orders shall be placed at the following level: the day before's market closure price +40% of the day before's candle movement.
Stop loss shall be placed 40 points below Buy Stop.
Sell Stop pending orders are placed the other way round: the day before's market closure price -40% of the day before's candle movement.
Stop Loss is placed 40 points above the value of the pending order Sell Stop.
The principle of drawing is as shown in the picture:
Please consider a very important moment: once one of the orders has been activated, the second one shall be deleted. Also, both orders shall be deleted if none of them triggered during the day. After covering the distance of 50 points, Stop Loss should be switched to a "loss-free" mode and trailed until it triggers, or you should fix profits at the closing of a session.
