are an adaptation of candlesticks which use averaging to filter out noise and better highlight trends.
As for candlesticks, values for Open, High, Low and Close are required.
H-Ashi Open = Average of previous H-Ashi Open and previous H-Ashi Close
H-Ashi High = Highest of High, H-Ashi Open and H-Ashi Close
H-Ashi Low = Lowest of Low, H-Ashi Open and H-Ashi Close
H-Ashi Close = Average of Open, High, Low and Close
Please note that due to the way the H-Ashi Close is calculated, the H-Ashi Close value for the last bar shown on the right-hand axis will not match the actual Close.
