EMA CROSS (HTF filter) by RA

This is EMA based indicator, gives buy sell signal on the crossover of EMA 1 (fast) & EMA 2 (slow). in this indicator EMA 3 and EMA 4 are optional but if you switch on the EMA 3 for trend direction, signal will be filtered by EMA 3. e.g. if trend is bearish according to EMA 3 and bullish crossover happens between EMA 1 & EMA 2 then no buy signal will be shown until price closes above EMA 3 and same logic for EMA 4.
This indicator is a Higher Time Frame (HTF) Trend filter indicator, if you switch on the the HTF filter then buy sell signal will be shown in alignment with the Higher Time Frame (HTF) Trend only, the best part is you can change HTF as per your requirement and there is toggle to on/off HTF.
