help with coding please, compiled but didn't appear as an indicator

protected override void Initialize()

//the sum of the volume of the last 30 bars
Var1.Set(SUM(Volume,30)[0]);
}
else
{
//minus the currentbar's volume that are false
Var1.Set(SUM(Volume, 30)[0] - Volume[0]);
}

//difine Var2
Var2.Set((Var1[0]/SUM(Volume, 30)[0])*100);


// draw the line according to the calculation
Plot1.Set( Var2[0]);
}

zhaofang8898,

You need to include all the indicator wrappers generated from the Indicator Wizard for it to work. Please ensure they are intact.

thanks for your reply, logic question please

trying to convert the code from another language to NINJA script, but couldn't follow the logic. the codes are:
// period = 30, if the current bar ' closing price > opening price, set the current bar's volume = 0
sum(if(close[0]>open[0], vol, 0), 30) / sum(vol, 30)

Not sure I follow what you are asking exactly. Don't know what you mean by setting a bar's volume. It will take on whatever volume is provided by the data provider.

[zhaofang8898]

what i mean was that i wanted to add the Volumes with the Closing price > Opeing price for a 30 bars period. during the past 30 bars, if the closing price < opening price, set the volume = 0 instead of the real volume. Can we do it in a loop method, or? not very sure about the how to write the logic in Ninja script language

zhaofang8898,

You cannot change the volume of a bar. You can only create your own DataSeries or plot and track the "fake volume" that you want in it.

You can create yourself a loop if you wanted. Please see this: http://www.ninjatrader-support.com/H...gCommands.html
