If the value of longbody is left as 0 (the default value), the candle function will automatically calculate the minimum longbody value as 2 times the 4-period ATR (average true range) for the given symbol and timeframe:
2 * iATR( symbol, timeframe, shift )
If the value of shortbody is left as 0 (the default value), the candle function will automatically calculate the maximum shortbody value as the 4-period ATR (average true range) for the given symbol and timeframe:
iATR( symbol, timeframe, shift )
The longbody and shortbody parameters can be set to any value using any combination of arithmetic and/or MetaTrader platform functions.
