Adjust an indicator logic for use in Strategy Builder

[MarcoNT29]

Hello,
How can I use this free indicator (here) as a condition to develop my own strategy on Strategy Builder?
I mean this indicator can calculate the closing percentage on the current bar and then brushes it, but instead of that I need that closing percentage condition in order to use it on Strategy Builder.

Something like this:
If this bar closes higher than 75%, go long ...

(I know how to use the Strategy Builder but I don't know what I need to add/edit to the indicator for the use I described above, and I don't want to unlock the code of my Strategy because I won't be able to edit it anymore)

Hello MarcoNT29,

Thanks for your post and welcome to the NinjaTrader forums!

The strategy builder would not be able to use the indicator. For the strategy builder to use an indicator, the indicator must provide a plot signal and the referenced indicator only colors the bars and does not provide a plot.

You could replicate the indicator coding in the strategy builder. The indicator uses these two conditions:

(For an upbrush): if(Close[0] >= Low[0] + BarPercent*(High[0]-Low[0]))

(For a down brush) if(Close[0] <= High[0] - BarPercent*(High[0]-Low[0]))

In both condition note that this calculation is the same: BarPercent*(High[0]-Low[0]) so it only needs to be done once

You would need to create a "custom series" in the strategy builder to "store" the calculation of BarPercent*(High[0]-Low[0]) on each bar.
The calculations would be done in two steps, first High[0] - Low[0] and store that value in the custom series, then takes that custom series value times the BarPercent and write that in the custom series. (The math is done using the "offset" feature).

You would create a user input for the BarPercent value (default is 0.75) (assuming you want to be able to change it)

The final calculation would be stored into two double type variables you could create (one for low and one for high)

LowCheck = Low[0] + customseries[0]
HighCheck = High[0] - customseries[0]

Next in one set create the condition of Close[0] >= lowcheck and in another set you would have Close <= highcheck

When those condition/sets are true you will have the same output as the indicator shows.

Thanks NinjaTrader_PaulH !
I have carried out the activities that you told me but the strategy does not do anything when I execute it .... Is something wrong?

Custom Series

Name: CustomS / Type: Double

Inputs

Name: BarPercent / Type: Double / Default 0.75

Variables

Name: HighCheck / Type: Double / Default 0
Name: LowCheck / Type: Double / Default 0

Conditions

Misc/Custom series/CustomS = Price/High/Arithmetic Offset - Close
Misc/Custom series/CustomS = Misc/Custom series/CustomS/Percent Offset BarPercent
User variables/HighCheck = Price/Low/Arithmetic Offset + CustomS
Price/Close >= User variables/HighCheck

Hello MarcoNT29,

Thanks for your post.

Sorry, I was not as clear as needed. The custom series values need to be assigned in the "do the following" section of a set.

Here are screenshots (i used different names but I think you will be able to follow.

In Set 1 there are no conditions, only the actions to assign values to the custom series and the 2 variables. the sequence of this set as the first is important. the calculations are done on each bar.



Set 2 contains a single condition and has the action to draw a colored dot that should align with a colored bar (by the indicator) as a way to test


Set 3 is the last set that contains the other condition and like set 2 contains an action to draw a dot that would correspond with a color bar (by the indicator) of the other direction.

Thank you very much NinjaTrader_PaulH !

The Strategy is working now... and I learned more than I thought!

I really appreciate your help
