help needed for indicator

[Novice6]

I am new to NT. I don't see any highest or lowest function, multiplication, nests, loops etc. in the "edit strategy" section of the control center.
How would I program in NT the following :

If position = 1 and

DMI+(13)[0] < 60% of highest ( DMI+(13) [since entry] )

then exit position

Welcome to our forums, you can use the MAX / MIN indicator methods for returning the highest and lowest values of a series. Multiplication and coding loops would need to be done in the NinjaScript editor then directly after for example unlocking your wizard started strategy.

For the position check you can use the MarketPosition one from the strategy category.
