This indicator is very useful for spotting trends / tops / bottoms.
This is the ultimate altcoin pump spotting tool. Use on higher timeframes for greatest accuracy. If altcoin is newish (ZEC for example), try 4h rather than 1D or 3D.
Green = Uptrend
Red = Downtrend
Gray = Top/local top, bottom/local bottom, or continuation. You will need some knowledge of price action to determine which condition applies.
You can use the oscillator at the bottom as a measure of momentum / trend strength. You can draw on the oscillator on the top/bottom or the interior.
