How many bars in screen?

[level2]

Hi there

Just a quick question?

How can I know how many bars are displayed in the chart currently???

I tried with Bats.Count but it seems to give me the TOTAL number of bars, not how many can be seen in this moment.

Thank you

level2, unfortunately there's no method for this.

NT7 was not released when this question was asked, so since it is here, is there now a way to count how many bars are currently on screen?

Hello Unhommefou,

Yes, NT7 now offers Count:

Edit: For bars on screen there is no supported property for this, but can try Koganam's suggestion.

int intFirstBarOnChart = ChartControl.FirstBarPainted;
int intLastBarOnChart = ChartControl.LastBarPainted;
int intBarsOnChart = intLastBarOnChart - intFirstBarOnChart;

You must be aware, and understand, that ChartControl access will not get any support from NT Support. They will not even answer questions about it.

Use at your own discretion.

This worked perfect for me just wanting the indicator printing on shown candles and not all the way back in history. I appreciate the tip.

In NT8 "FirstBarPainted" and "LastBarPainted" are no members of the ChartTrader object anymore. Is it possible to retrieve the values with NT8?

Would suggest for NT8 now you peek into the ChartBars class's FromIndex and ToIndex - https://ninjatrader.com/support/help...?chartbars.htm

bandass,

This could be done in OnRender(). Please see the example of looping through the charts visible bars in this helpguide link: https://ninjatrader.com/support/help..._fromindex.htm

if a chart has 100 bars of data, the very first bar of the chart (left most bar) will be number 0 (zero) and each subsequent bar from left to right is incremented by 1.

Hello samanthagates29,

Welcome to the NinjaTrader forums!

The very first bar of data is bar 0. This would be the first bar if the chart is scrolled all the way to the left.
However, if the chart is not scrolled all the way to the left, the first visible bar is ChartBars.FromIndex.
