Hello denymachado,

Thanks for your post.

To draw a line on the chart you could use the Line drawing tool found in the Strategy Builder by going to Conditions and Actions screen > Actions section > add > Drawing folder > Line.

The 'Start Y' and 'End Y' properties could be set to the High price (Price folder > High) to draw the line at the High of the bar. You could set the 'Tag' property to use a unique tag name, such as using 'Current bar' (Misc folder > Current bar), each time the method is called so a new line is drawn on each bar.

The 'Start Y' and 'End Y' properties could be set to the Low price (Price folder > Low) to draw the line at the Low of the bar.

I have attached a simple Strategy Builder script that demonstrates drawing a line at the High of a bar. You could view the script to see how this is accomplished and then implement similar logic to draw a line at the Low of a bar.

See the help guide documentation below for more information.

Thank you for the fast response it did work, but it was slowing my charts I guess its too much calculation, would that be a way to have the lines only on the current candle ? or Erase the past lines ?

Hello denymachado,

Thanks for your notes.

To have the lines drawn only on the current bar, you could give the Draw.Line() methods a static Tag name instead of a unique Tag name.

For example, you could remove 'CurrentBar' from the Tag name of the Draw.Line() method in the sample script shared on post # 2 so that the Tag property is only "Line".

See the 'How to draw on chart' section of this help guide page: https://ninjatrader.com/support/help...t8/actions.htm

denymachado If I have understood correctly, you would like to draw a line for the high and low of each bar. This is because drawing a Line on Close only draws a line through the closing price and not the high price or the low price of the bar.

Here's a workaround that I came up with.

1) Add the stock Ninja SMA to your chart. Change the period to 1.
2) Select the instrument you want to use as the Input Series.
3) In that same window on the right, select High or Low as Price Type. (see second screenshot)
4) Repeat steps 1-3 but select Low for step 3.

The third screenshot shows the solid red line as just the instrument plotted as Line on Close. The dashed line now plots the high of each bar.

Hope this helps.

P.S. NinjaTrader_BrandonH I just wish Ninja would allow plotting multiple standardized lines/instruments/indicators with dissimilar unit scales in overlay mode. Currently, it just allows one per left, right or overlay scale.

Hello oldporkchops,

Thanks for your notes.

To clarfy, do you want to have the same indicator to plot multiple plots on the chart calculated from different values, such as Close, High, or Low?

If so, you could add multiple instances of the same indicator to the chart, set each indicator instance to 'Overlay', set the Dash style you want each indicator instance to use, and set the Input series you want each of the indicators to calculate from.
