Look on the image:
- blue line is RSTL (Reference Slow Trend Line) which is 'Support Slow Trend Line';
- white line is RFTL (Reference Fast Trend Line) which is 'Support Fast Trend Line';
- and SuperTrend indicator.

Yes, hua, you are right, Supertrend together with RSTL is more good than RFTL and RSTL. But as I understand it is the filter systems only to filter some signals. We may use it in an other systems.

But look on the MACD+OSMA indicator (see image) It is almost the same with this Supertrend and RSTL. Filter.

Some people say that trading system based on the filters only may be profitable for the short period of time.

Anyway we may use this system as a filter or just select an other indicators for this SuperTrend-RSTL or MACD+OSMA. May be.
