Question regarding previous day High, low and close

[Muddy]

Hi everyone,

I needed a little help on a step for a strategy I'm currently developing.

The strategy involves hardcoding some price levels into the where i'd like to take profit. The data required for the lines is the high low and close, for the previous day, 2 days before and 3 days before. Also, I don't want it to be a rolling 3 days, which I guess could be done be specifying the number of bars in 24 hours and using the MAX() and MIN() functions. I shall include the code of what I have tried to solve below, however I keep getting 'an object reference is required' error.

The code I have tried to run so far is:

public double d1p = (Bars.GetDayBar(1).High + Bars.GetDayBar(1).Low + Bars.GetDayBar(1).Close)/3;
public double d2p = (Bars.GetDayBar(2).High + Bars.GetDayBar(2).Low + Bars.GetDayBar(2).Close)/3;
public double d3p = (Bars.GetDayBar(3).High + Bars.GetDayBar(3).Low + Bars.GetDayBar(3).Close)/3

Any help is much appreciated!

Hello Muddy,
Thanks for posting today.

If these variables are initialized in the variables region for the indicator they will not be able to reference the Bars object.

You can initialize this variable to some value and then set in another method.

For example.

#region variables
private double d1p = 0;

...

OnBarUpdate()
{
double d1p =(Bars.GetDayBar(1).High + Bars.GetDayBar(1).Low + Bars.GetDayBar(1).Close)/3;

...}

Please let us know if we may be of further assistance for anything NinjaTrader.

Hi Alex,

Thanks for the quick response - I'm not actually using an indicator as such - I'm using the equations on which the indicator is based to hard code in limits (which aren't plotted or anything) around which I base my strategy. Basically specific prices I want to see crossed or to take profit at. I tried moving the variables into the onbarupdate() section, however now the inequalities I wish to base my strategy on are getting errors regarding invalid tokens and 'Array size cannot be specified in a variable declaration'. Thanks again for taking the time to help!
