A small alteration to your high-low-channel-BT:
conditions for candle-colour:
If price is above LWMA200-high-low and candle closes above LWMA9: candle colour up (i. e. buy) - colour remains until candle closes below LWMA9
If price is below LWMA200-high-low and candle closes below LWMA9: candle colour down (i. e. sell) - colour remains until candle closes above LWMA9
Maybe you like the idea and think it improves signals. If you don't like the idea just forget about it.
