Things I would add to your system.
1. Know what time of day your favorite pair consolidates..
2. Know the time of day your pair get active.. (usually when the local banks open)
2. Know what time of day reversals typically happen on your pair… its often like clockwork..
3. Know how much your pair moves during average session for Asia, london, and usa sessions.
Certain pairs often follow a pattern based on time of day, and traders will often take a long break when the average movement is reached.
If you find like one session more then another, focus your energy where you are having the best luck.
use your levels, with some timing.. and you got a system!
The only system that will work is one designed by and for yourself.
