    Testing of Mr Larry Williams Formula

    Hi Everybody,

    I am testing the Larry Williams formula for entry strategy of
    following:
    Larry Williams Formula
    Inputs: Length(16),
    PH( ( ( (H+L+C) / 3) * 0) - L),
    PL( ( ( (H+L+C) / 3) * 0) - H);


    But is not working. Can anybody help to find out
    what is wrong.
    Thank you very much.


    #region Variables

    private DataSeries williamPH ;
    private double william_PH_highestValue = 0;

    protected override void Initialize()
    {
    williamPH = new DataSeries(this);

    CalculateOnBarClose = true;

    }
    protected override void OnBarUpdate()
    {

    //LONG CRITERIA


    if (Position.MarketPosition == MarketPosition.Flat)
    {
    SetStopLoss("PositionLong1",CalculationMode.Ticks, 20,false);
    SetProfitTarget("PositionLong1",CalculationMode.Ti cks, 10000);

    }

    // Resets the highest high at the start of every new session
    if (Bars.FirstBarOfSession)

    williamPH[0]= ( ( ( (High[0]+Low[0]+Close[0]) / 3) * Open[0]) - Low[0]);


    // Stores the highest high from the first 16 bars
    if (Bars.BarsSinceSession < 16
    && williamPH[0] >William_PH_highestValue )
    {
    William_PH_highestValue = williamPH[0];
    }

    // Entry Condition: Submit a buy stop order one tick above the first 30 bar high. Cancel if not filled within 34 bars.
    if (Bars.BarsSinceSession > 16 && Bars.BarsSinceSession < 50
    &&Position.MarketPosition == MarketPosition.Flat)
    {
    EnterLongStop(DefaultQuantity, William_PH_highestValue+2*TickSize,"PositionLong1" );
    InitialStopPrice = Low[1]-100*TickSize;
    ProTarget =2.5*( InitialStopPrice);

    SetStopLoss("PositionLong1", CalculationMode.Price, initialStopPrice, false);
    SetProfitTarget("PositionLong1", CalculationMode.Price, ProTarget);
    }

    }

    Hello ArthurMFTse,

    Thank you for your post and welcome to the forums!

    You would want to some run debugs through your script to ensure that you are getting the correct results from your calculations that you are expecting -

    First of all you would want to use Print() statements to verify values are what you expect - Debugging your NinjaScript code.

    It may also help to add drawing objects to your chart for signal and condition confirmation - Drawing Objects.

      The formula is false. (H+L+C) / 3) * O) would be a squared price and have a false dimension. The correct formulas for projected high and low are

      PP = (H + L + C) / 3
      PH = PP * 2 - L
      PL = PP * 2 - H

      Those levels are identical with the floor pivots R1 and S1. If you wish to calculate them from the regular session high, low and the settlement price, please use the SessionPivots indicator that can be found in the download section.
