This is a multi-timeframe Parabolic SAR indicator which uses 1 and 4 hour charts.
Using this indicator is simple, if the LifeTime line is green then buy, if red then sell OR don't trade. So...
Green Line - This strategy is in a buy position Red Line - This strategy is in a sell position Any other colour - DON'T TRADE
The traders approach is simple, when all indicators are green or red, then take the trade. As soon as one indicator changes, then re-evaluate using your normal process, such as price action, to determine whether to close the trade or continue.
