First of all, a huge credit to Wade for all the help with this indicator. An absolute Legend!
The idea behind this indicator is to identify a potential trend with simply the close of candles. If a candle closes above the previous candle High, the trend would be "bullish" and remain bullish until there is a candle that closes below the previous candle Low. The opposite is true for a "bearish" trend.
As always, this is NOT intended to be used by itself, but with other TA.
For cleanest results, I find it best to use with the candle borders turned off in the chart settings but that is just my preference.
