(CurrentBar == 0)

[jriverac]

Hallo,

What does (CurrentBar == 0) mean?. In the MACD indicator, it says:

if (CurrentBar == 0)
{
fastEma.Set(Input[0]);
slowEma.Set(Input[0]);
}

I though the CurrentBar index started from 1.

Incorrect, starts at 0.

But in The NinjaTrader Help it says_
CurrentBar
Definition

A number representing the current bar in a Bars object that the OnBarUpdate() method in an indicator, Market Analyzer column or strategy is currently
processing. For example, if a chart has 100 bars of data, the very first bar of the chart (left most bar) will be number 1 (one) and each subsequent bar from
left to right is incremented by 1.

I am getting confused with something here: In the MACD, when it says:
if (CurrentBar == 0)
Is it refering to th every first bar of the chart, or is it refering to the last bar available (the very last bar)??

Not sure which docs you are looking at. I have latest 6.5.1000.2 installed and see this: http://www.ninjatrader-support.com/H...urrentBar.html

Ok, I see. there was a mistake in the older version of the Help.

Talking about mistakes, in the tutorial Level 4 for indicators, when entering the Calculation Logic and it says:

// Calculate the range of the current bar and set the value
Plot0.Set(SMA(SMAPeriod)[0] + myDataSeries[0]);

is that expression correct??

Thanks!

What's wrong there?

[jriverac]

Should it not be?

Plot0.Set(SMA(myDataSeries,SMAPeriod)[0];

Not sure I follow. Statement below is syntactically incorrect.
