try adding:

SetBarsRequired(-2,-2);

at the top of your code.

  Hi,

  I have noticed that chart signals sometimes disappear when I interact with 
the chart, e.g. when I click on it or scroll it.

  Here is an example of a script where this problem occurs:

  // Script Start

  SetPositionSize(20, spsPercentOfEquity);
  SetTradeDelays(1, 1, 1, 1);

  BuyPrice = SellPrice = O;

  HHP = 16;
  LLP = 5;

  HH = Ref(HHV(C, HHP), -1);
  LL = Ref(LLV(C, LLP), -1);

  Buy = Cross(C, LL) AND BarCount > 248 * 2;
  Sell = Cross(HH, C);

  Buy = ExRem(Buy, Sell);
  Sell = ExRem(Sell, Buy);

  Plot(HH, "HH", colorLightBlue, styleLine);
  Plot(LL, "LL", colorLightOrange, styleLine);
  PlotShapes(shapeUpArrow * Buy, colorBrightGreen);
  PlotShapes(shapeDownArrow * Sell, colorRed

  // Script End

  Can anyone assist with this, please?
