Big candles
This tool identifies "big" candles. Whether a candle is big or not can be decided by
                  using the average true range (ATR). The ATR indicates the
                  volatility of an instrument. The trader can take the ATR over,
                  for example, 20 periods and request the platform to highlight
                  those candles which are bigger than, for example, 2 times the
                  ATR.
                

Trader Erdal Cene uses big candles, which he calls monster candles, to help him determine the progress of a trend.
If in an uptrend a big red candle occurs it is an indication for him that the regression is finished and the next progression arm of the ZigZag is about to start. So traders should consider placing buy orders.
Erdal Cene does not specify a rule to identify big candles. Being very experienced he identifies them visually. The big candles tool in the platform identifies big candles for you.
This example
                  shows a 60-minute chart on the DAX. The one candle which is
                  considered a big candle is automatically highlighted by the
                  big candle tool.
