The indicator will highlight the Extended Range Candles (ERC) price gap. Extended Range is the price excessively moving in one direction, it can be one or more candles. ERC Gap is the range of price that doesn’t have any resistant.
To classified as ERC I use the range (highest price minus lowest price) of the candle before the ERC and divide with ERC range. If result less than given percentage (ERC %) then confirm it is ERC.
