. The reason for this is that actual price data is lost, since the candles are more akin to a moving average than a different way to see price action. Also, with Heikin Ashi, most of the actual price action is lost, because the candles can be bigger than the high and low of the underlying japanese .
With BERLIN Candles I have tried to fix that problem. By using a smoothed out version of the previous Heikin Ashi candle close as the current BERLIN Candle open, the high and low of the actual japanese for the high and low of the BERLIN Candle, and the current Heikin Ashi close as the BERLIN Candle close, while setting hard limits for BERLIN Candle open and close values so that they can never exceed the high and low of the underlying japanese .
One problem still persists though. The actual current price data is lost. However, the BERLIN Candles have solved this by adding a fifth part to the candles. The close of the underlying japanese are indicated with a plus-sign. This way, actual price data is never lost, while keeping all of the other benefits of this type of candles.
