  Cant seem to get my tradingview bollinger band to match my prorealtime setup. Please help, this is the trading view code in attachment.

  My settings are Length 10, std dev 0.66, source – close, offset – 1  from tradingview

  Different data in equals different result out. Unless your Tradingview is getting the exact same data from the exact same broker as your PRT platform is then why would you expect the same result?

  Also please don’t expect people to download TXT files. Post the code directly in your post.

  That needs a custom coding, here is the code for that kind of bollinger bands (short term, 0.66 factor for the upper and lower bands and offset by 1 period):

  avg = average[10] istd = std[10] up = avg+istd*.66 dn = avg-istd*.66 return up[1],dn[1]

  1 2 3 4 5 6

  avg = average[10] istd = std[10] up = avg+istd*.66 dn = avg-istd*.66   return up[1],dn[1]

  Hi sorry heres the code –

  //@version=4
  study(shorttitle=”BB”, title=”Bollinger Bands”, overlay=true, resolution=””)
  length = input(20, minval=1)
  src = input(close, title=”Source”)
  mult = input(2.0, minval=0.001, maxval=50, title=”StdDev”)
  basis = sma(src, length)
  dev = mult * stdev(src, length)
  upper = basis + dev
  lower = basis – dev
  offset = input(0, “Offset”, type = input.integer, minval = -500, maxval = 500)
  plot(basis, “Basis”, color=#872323, offset = offset)
  p1 = plot(upper, “Upper”, color=color.teal, offset = offset)
  p2 = plot(lower, “Lower”, color=color.teal, offset = offset)
  fill(p1, p2, title = “Background”, color=#198787, transp=95)
