a problem with heikin-ashi formula

  hi gentlemen,

  i have a question, i have written a simple code to detect inside bars of the same colour on heiken-ashi.

  but the screener, i think, sometimes give me inconsistent results. below are the formulas that i use.

  can you check it out for me where i did wrong for example? or it’s the fault of screener?

  heikin ashi inside bar

  //inside candle of HA, long or short myhaopen = CALL "ha-open" myhaclose = CALL "ha-close" //go long c1 = myhaopen > myhaclose c2 = myhaopen[1] > myhaclose[1] c3 = myhaopen < myhaopen[1] c4 = myhaclose > myhaclose[1] //go short c6 = (c1 and c2 and c3 and c4) c7 = myhaopen < myhaclose c8 = myhaopen[1] < myhaclose[1] c9 = myhaopen > myhaopen[1] c10 = myhaclose < myhaclose[1] c12 = (c7 and c8 and c9 and c10) screener [c6 or c12]

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25

  //inside candle of HA, long or short   myhaopen = CALL "ha-open" myhaclose = CALL "ha-close"   //go long   c1 = myhaopen > myhaclose c2 = myhaopen[1] > myhaclose[1] c3 = myhaopen < myhaopen[1] c4 = myhaclose > myhaclose[1]   //go short   c6 = (c1 and c2 and c3 and c4)   c7 = myhaopen < myhaclose c8 = myhaopen[1] < myhaclose[1] c9 = myhaopen > myhaopen[1] c10 = myhaclose < myhaclose[1]     c12 = (c7 and c8 and c9 and c10)   screener [c6 or c12]

  ha-open

  c1 = (open[1]+close[1])/2 return (c1)

  1 2 3

  c1 = (open[1]+close[1])/2   return (c1)

  ha-close

  c1 = (open+close+high+low)/4 return (c1)

  1 2 3

  c1 = (open+close+high+low)/4   return (c1)

  thank you.

  This is not the correct formula for Heikin Ashi candlesticks, please use the one below:

  xClose = (open+high+low+close)/4 if BarIndex=0 THEN xOpen = open xHigh = high xLow = low else xOpen = (xOpen[1] + xClose[1])/2 xHigh = Max(Max(high, xOpen), xClose) xLow = Min(Min(low, xOpen), xClose) endif

  1 2 3 4 5 6 7 8 9 10

  xClose = (open+high+low+close)/4 if BarIndex=0 THEN xOpen = open xHigh = high xLow = low else xOpen = (xOpen[1] + xClose[1])/2 xHigh = Max(Max(high, xOpen), xClose) xLow = Min(Min(low, xOpen), xClose) endif

  Xopen and Xclose in your case.

  one final question: yes now the formula works but does not include dojis. i put the equal sign but again it does not work (for the dojis).

  for example on 14/10/2022 doesnot show BRENNTAG stock on dax40.

  where am i wrong? thank you!

  about dojis

  //inside bar on S+R of the same color on H.A. //real formula for open+close of H.A. xClose = (open+high+low+close)/4 if BarIndex=0 THEN xOpen = open else xOpen = (xOpen[1] + xClose[1])/2 endif //go long c1 = xOpen >= xClose c2 = xOpen[1] > xClose[1] c3 = xOpen < xOpen[1] c4 = xClose > xClose[1] c6 = (c1 and c2 and c3 and c4) //go short c7 = xOpen <= xClose c8 = xOPen[1] < xClose[1] c9 = xOpen > xOpen[1] c10 = xClose < xClose[1] c12 = (c7 and c8 and c9 and c10) screener [c6 or c12]

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27

  //inside bar on S+R of the same color on H.A. //real formula for open+close of H.A.   xClose = (open+high+low+close)/4 if BarIndex=0 THEN xOpen = open else xOpen = (xOpen[1] + xClose[1])/2 endif   //go long c1 = xOpen >= xClose c2 = xOpen[1] > xClose[1] c3 = xOpen < xOpen[1] c4 = xClose > xClose[1]   c6 = (c1 and c2 and c3 and c4)   //go short c7 = xOpen <= xClose c8 = xOPen[1] < xClose[1] c9 = xOpen > xOpen[1] c10 = xClose < xClose[1]   c12 = (c7 and c8 and c9 and c10)   screener [c6 or c12]

  Hi @gnellas77

  Try this one…

  now it catches the pure doji of BRENNTAG and the small doji of FRESENIUS but misses SYMRISE and DELIVERY HERO which have an inside bar of the same colour. That was the objective from the beginning to catch both inside bars and dojis at the same time.

  i would like to have one formula for both cases. Do i have to use them seperately? by the way are the variables of xHigh and xLow necessary once i m only interested in the bodies of the candles?

  thank you!!!

  The body of the Doji is theoretically equal to zero when the Close = Open.

  However, this will rarely (never?) occur and that is why you express the body of the Doji in a percentage of the range (xHigh – xLow).

  For the inside bar you first have to determine whether you are looking for a “Bull Candle (xOpen < xClose)” or a “Bear Candle (xOpen > xClose)”.

  So, you have to add an extra condition.

  Examples of Doji spotted with Heikin Ashi formula, and with percentage of body compared to the range:

  your help was very useful. thank you very much!!!
