Can someone help with a study that draws two white lines at the High and Low of a candle, if the next 4 candles are completely inside its range? Lines should have approx. length of 5 bars. If it's easier it can also just color the first candle or otherwise visually indicate. See image example of two white lines to indicate a small range.

Is this possible to do within SC or do I need to find someone to code this as a study? Thanks

This would require a custom ACSIL study.

Hi,

Please, how do you use the concept in this indicator ?

Hi, you can use the built-in Color Bar Based On Alert Condition Study to achieve this.

In the Alert Conditions Tab, enter this:

 

Code

AND( H > H[1], H > H[2], H > H[3], H > H[4], L < L[1], L < L[2], L < L[3], L < L[4] )

Cheers!

PS: If you are interested, I can post the code for an ACSIL study to draw lines like in your example.

Thanks for your response.

You seem to be talking in Sierra dialect; I use NinjaTrader 8. So, could you please translate your Sierra logic code snippet to NinjaTrader 8, or in just a simple English description.

Sorry, I don't know how to do this in NT. You probably need to code this. The OP was asking for a Sierra Chart solution for this.

Grok is your friend.... This may indie may be backwards to your intent but you can have Grok mod it however you like.

q: hey Grok can you make an engulfing bar indicator which will draw white extension lines at the highs and lows of the engulfing bar based on how many bars you set it to look for. n=2 would would draw lines when engulfs at least 2 bars, etc. in ninjatrader 8 script.

a: Below is a NinjaTrader 8 script for an engulfing bar indicator that draws white extension lines at the highs and lows of an engulfing bar when it engulfs at least n bars, as specified by the user. The script uses the NinjaScript framework to detect bullish and bearish engulfing patterns and draw horizontal lines extending to the right.

Explanation:
Purpose: The indicator identifies bullish or bearish engulfing bars that engulf at least n previous bars (set via the BarsToEngulf parameter) and draws white horizontal lines at the high and low of the engulfing bar.

Engulfing Logic:
A bullish engulfing bar has a higher close than open, and its body (open to close) and wicks (high to low) must fully encompass the bodies and wicks of the previous n bars.

A bearish engulfing bar has a lower close than open, with the same engulfing criteria.

Drawing: Uses Draw.HorizontalLine to draw white lines at the high and low of the engulfing bar, extending to the right (default NinjaTrader behavior for horizontal lines).

Parameter: BarsToEngulf (default = 2) allows the user to specify how many bars the engulfing bar must engulf.

Safety: Checks for sufficient bars (CurrentBar < barsToEngulf) to avoid index errors.

Calculation: Runs on bar close (Calculate.OnBarClose) to ensure complete bar data.

How to Use:
In NinjaTrader 8, go to Tools > Edit NinjaScript > Indicator.

Create a new indicator and paste the above code.

Compile the script.

Add the indicator to a chart via Indicators menu.

Set the Bars to Engulf parameter (e.g., 2) in the indicator settings.

Apply the indicator to see white lines at the highs and lows of qualifying engulfing bars.

Notes:
The lines persist until manually removed or the chart is refreshed, as they are drawn with unique tags (HighLine/LowLine + CurrentBar).

Ensure the chart has enough bars to evaluate the BarsToEngulf setting.

If you want the lines to extend only a certain number of bars to the right, you’d need to modify the script to use a custom drawing tool or manage line removal, which can be added if needed.

Let me know if you need adjustments, like limiting line duration or adding visual markers!
