3 simple moving average system

This is a very simple system based on 3 SMA close breaks 7 SMA high or low the entries and exit are based on below rule.


Long

when 3sma close touched and bounced above 7sma low, target or exit when price touches 7sma high. OR price fall below 7sma high

Short

when 3sma close touched and fall below 7sma high, target or exit when price touches 7sma low. OR price raise above 3 sma low

I have circle all convergence of 3sma close either on 7sma high or low. This can be used for swing trading too. IS IT SIMPLE?
