How the filter works- ema per 5 gives arrows frequently then higher ema settings on macd crossovers

Red arrow (lower-timeframe MACD crosses below 0): it shows only if the candle it sits on is the strong red, C’200,50,100'.
Green arrow (MACD crosses above 0): it shows only if that candle is the strong blue, C’50,150,255'.
In every other case the arrow is hidden. That includes white candles and the light red (255,160,160) and light blue (160,200,255) candles, which are not the strong colours you named.
