Trying to understand what this PlotPercentP formula is doing so I can plot inside Ninjatrader, any help is appreciated. Thx in advance.

variables:
    intrabarpersist bool PlotPercentP( false ),
    double LowerBandP( 0 )                    , 
    double UpperBandP( 0 )                    ,
    double PercentP( 0 )                                     ;         
once
    PlotPercentP = GetAppInfo( aiApplicationType ) <> cChart ;
LowerBandP = Lowest( Low, Length )[1]                        ;
UpperBandP = Highest( High, Length )[1]                      ;

Hello,
Thanks for posting today.

We do not support other languages that not are NinjaScript. I am not familiar with Easylanguage but it appears that

LowerBandP = Lowest( Low, Length )[1]

is plotting the lowest of the low over a length (period) of time. However, I could be wrong on the logic behind this indicator. I am unsure how the PercentP is then calculated.

If you are able to figure out what the plot is logically doing I could then help you apply the logic using NinjaScript principles.

You may want to look at the code for the DonchianChannel indicator that should be supplied in NinjaTrader. That might give you some ideas on how to do what you want.

Please check my Ninja code?

Could you please check my code to see if I am correct please?

1) In order to have the linear regression value of the close over 21 bars?

= LinReg(21)[0]

2) How do I average the value from 1) with a smoothing length of 3?

= EMA(LinRegValue,3)[0];

3) How do I get the Standard Error Average of the close over 21 bars with a smoothing length of 3?

= ((StdError(21).Upper[0] - StdError(3).Lower[0])) / 2;

TradeTheBonds,

You should just go to the Help file on LinReg, EMA and StdError. There are examples.

Yes I have tried the examples, from the help file, but they are not giving me the same values as the ones I am printing from my Tradestation code. So I must not have this correctly interpreted. But appreciate the help Jerry,

I see the MAX & MIN in DochianChannel you had referred to, I appreciate that very much.
Have a great big slice of the market today, will ya!

Use a print statement in both the tradestation and Ninja code to print all the values , EMA , LinReg, StdError, etc. along with the symbol data you are passing it and the date and time so you can match them up to see what is going wrong.

Hello,

As JerryWar said

Use a print statement in both the tradestation and Ninja code to print all the values , EMA , LinReg, StdError, etc. along with the symbol data you are passing it and the date and time so you can match them up to see what is going wrong.

Use the print statement to compare the outputs and see where the variance is within the NinjaTrader code vs the Trade Station.

Here are some links to the help guide discussing the methods that JerryWar mentioned.

Are you sure your data is exactly the same?
