I wrote the Heiken Ashi K average code.

{—HEIKEN ASHI K LINE—}

XC: = (C+H+L+O) /4;

XO: =TMA (REF (XC,1) ,0.5,0.5);

XH: =MAX (H, MAX (XC, XO));

XL: =MIN (L, MIN (XC, XO));

DRAWKLINE (XH, XO, XL, XC);

{—HEIKEN ASHI K LINE—}

Experience: XC: = (C+H+L+O) /4 in MOOM; however, since institutions use the quantitative effects of raising stock prices before and after the market to control the opening price and influencing stock price trends, there is no need for an opening price. It is OK to use this K-line as an auxiliary analysis.
