Switch indicators on/off

  Could anyone tell me if there is a way to show or hide an indicator based on conditions relating specifically to the current candle only?

  e.g.
  If low<EMAx and close>EMAx then display EMAx.

  I did try a custom EMA indicator but the the EMA only displayed on each candle in the past which met the criteria rather than just plotting the EMA on the chart.

  Thanks.

  Try this one (not tested):

  MyEma = average[20,1](close) t = 0 //transparency = invisible If low < MyEma and close > MyEma then t = 255 Endif Return MyEma coloured(0,255,0,t) as “MyEma”

  1 2 3 4 5 6

  MyEma = average[20,1](close) t    = 0   //transparency = invisible If low < MyEma and close > MyEma then    t = 255 Endif Return MyEma coloured(0,255,0,t) as “MyEma”

  it takes advantage of the optional 4th COLOUR parameter, transparency (0-255), to make ema visible only when conditions are met.

  Hi,

  Unfortunately this is still only displaying the MA on candles which meet the criteria.

  Isn’t that what you meant with “If low<EMAx and close>EMAx then display EMAx”?

  Sorry, I didn’t make it clear.

  I want to be able to display MA[x] on the whole chart but only if the last day’s candle meets the requirements.

  So if today meets the conditions then MA[x] is displayed on the whole chart.

  Hope that makes sense!

  There’s no instruction to achieve that, so it must be coded.

  I’ll make it asap.

  Bob’s your uncle:

  DEFPARAM DrawOnLastBarOnly = True Periods = 20 //Ema periods LookBack = 200 //plot Ema on the last 200 bars MyEma = average[Periods,1](close) If low < MyEma and close > MyEma then FOR i = (LookBack - 1) DownTo 0 j = i + 1 DrawSegment(BarIndex[j],MyEma[j],BarIndex[i],MyEma[i]) coloured(0,255,0,255) style(Line,3) NEXT Endif Return

  1 2 3 4 5 6 7 8 9 10 11

  DEFPARAM DrawOnLastBarOnly = True Periods  = 20      //Ema periods LookBack = 200     //plot Ema on the last 200 bars MyEma = average[Periods,1](close) If low < MyEma and close > MyEma then    FOR i = (LookBack - 1) DownTo 0       j = i + 1       DrawSegment(BarIndex[j],MyEma[j],BarIndex[i],MyEma[i]) coloured(0,255,0,255) style(Line,3)    NEXT Endif Return

  Line 2 are the Ema periods and Line 3 are the number of bars you want the Ema to be plotted when conditions are met.
