Automatic Trend Line Detection and Alert

[NinjaTrader_Ray]

There is no trading methodology on this indicator. Its purely a visual that draws trendlines and alerts you to a break. Interpret as you see fit.

Does anyone understand the methodology of using this indicator?
When it gives a long trendline are you supposed to go long?
Or wait until it goes long and gives the arrow of breaking the trend then go short?
What is the arrow breaking the trendline supposed to signify exit the line trend or go other direction?
Thanks

Hi Apat1,

It is set to true in the code and also in the properties window by default. But I see it gives signal even before a bar closes below the trend line. Not sure what to change to fix it, so that it gives signal only when a bar "closes" below trendline.

Thanks

If it is set tof alse the calcs are on incoming tick basis.
Probably can change it in the indicator prop window.

Hi Ray,

In line 42, it is already set to true.

Thanks
RK

[NinjaTrader_Ray]

Line 42 should be set to 'true'.

[RK_trader]

Thanks Ray. I am still in learning phase of Ninja programming.

I see "calculateonbarclose" on line 42 in Initialize() and it is set to true

And the other place I see it is on line 298 which says as below:

indicator.CalculateOnBarClose = CalculateOnBarClose;

Can you please clarify as to in which line, I need to change the value to true, so that it waits for a a bar to close below the trendline to give the alert.

Appreciate your time on this.

Thanks

The indicator waits for the first value lower or higher than a uptrend or downtrend line. If the indicator's "Calculate on bar close" is set to true, it will wait for a close of the bar otherwise just the first tick.

Unfortunately I will not be ammending the code to provide extra user defineable parameters however, anyone can take this open source code and modify it as they wish.

Thanks Josh for the quick reply. No problem.

I would appreciate opinions/comments on people who are actively using this indicator. Any volunteers who can modify the code to get the enhancements/options.

Thanks

Unfortunately I cannot provide assistance on this indicator RK_trader. It wasn't me who programmed this one and so I do not know what the parameters do or mean.

Hi

Any active users of this auto trendline indicator, did you experiment with what "strength" property value you are getting good results? I tried 5 and not sure if it is good.

Also when does it give the signal. Does it wait for atleast one bar to close below the current trendline?

Josh thanks for good indicator. I am not a Ninja programming expert, trying to learn the indicator programming. Is it possible you can modify the indicator to include a property field "the number of bars to close below trendline to give signal"

Also I would like to request if you are considering enhancements to make the trendline a little below the swing lows with a "displacement". For example in an uptrend the trendline is joining the swing low pivots. I am finding that if the trendline is a bit conservative and like a few ticks below the swing lows, it is holding well. For example, if the swing lows in ES uptrend are like 1531.50, 1535.50, 1540.50, then a line joining 1531.25 ,1535.25,1540.25 with 0.25 displacement to downside is holding really well and when it breaks, it gives a very strong signal and doesn't give false signals. May be this can be enhanced by adding a "displacement field" to properties.

I appreciate your time and any active users opinion on this.

Thanks

Thanks Josh. I appreciate it.

Do you know what the "strength" field indicates? Does it indicate number of swing pivots needed for drawing the trendline?

Did you test whats the optimum strength field for ES 3 min chart. Appreciate your time on this.

Thanks

Strength represents the number of bars left and right of a pivot required to form a pivot. I have not done any optimization to determine best values on any time frame.

The reason it is trying to overwrite the Swing indicator is because the way the export NinjaScript is designed is to allow the export file to work on its own. You can safely overwrite your Swing indicator as it is the same file. There will be no changes done.

Thanks Ray for the auto trendline indicator.

When I tried to install it is trying to overwrite the default "swing"indicator, is this expected? Does it change swing indicator in anyway?
