Possibility to Develop through Strategy Builder

[futtrader]

Hello

I am new to Ninjatrader and want to know whether following scenario is possible using Strategy Builder UI ?

Scenario1:

PreviousBar is Green and LengthOfPreviousBar >= ATR() * 2


PreviousBar is Red and LengthOfPreviousBar >= ATR() * 2



Scenario2:
User Provide input
LookBackBar = N
assume N = 5

Low[1] >= Low[2] >= Low[3] >= Low[4] >= Low[5] to check 5 consecutive Bar is have Higher Low to check Uptrend

Similarly

High[1] <= High[2] <= High[3] <= High[4] <= High[5] to check 5 consecutive Bar is have Lower High to Check Downtrend

Here use will decide value of N

Hello futtrader,

Thank you for your post.

For scenario 1:

You can determine is the previous bar was green by checking if the Close price was greater than the Open price for that bar. The previous bar was red if it's Close price was less than its Open price.

You can calculate the 'length' of a bar by subtracting the Open price from the High price, then dividing that by the TickSize. Due to the limitations of the Strategy Builder this can be complex. You will need 2 additional custom series to calculate this in order to use Offset math. Please see the attached screenshot.

Save this value to a variable in a separate condition set, then you can use this saved value to the value of the ATR offset by * 2 in another set. You can create variables from the 'Inputs and Variables' screen.


For scenario two:

You can define user inputs in the 'Inputs and Variables' tab, and give each one a default value.

You can add to each condition set that the input variable has to have a specific value in order for the conditions to evaluate as true, to turn some conditions off an some on.

For example, in one set you check if your user input N == 5, then your conditions can check if Low[1] >= Low[2] >= Low[3] >= Low[4] >= Low[5]. If N is not 5, this condition set will not be evaluated.

In another set check if N == 4, then also check if Low[1] >= Low[2] >= Low[3] >= Low[4]. Similar logic can be implemented for other sets checking if N = 3 or 2.

thanks but for the second scenario, it still kinda hard coding --if I want to keep range of N from 1 to 100 it's too much work to create 100 set for the N.

Hello,

Unfortunately, it may be necessary to unlock the code using the 'Unlock Code' button and code this by hand in order to achieve the logic you're looking for. The Strategy Builder is meant for simple logic and has limitations.

If you unlock the script, you could use a for loop to accomplish your logic.

Please let us know if you have any other questions.
