How do I get the maximum Equity Value over a period?

I have tried with MaxVal but not sure how pointers work:
vars max_value = series(MaxVal(Equity,500)); //Error - MaxVal(): Pointer expected

Any ideas?

Thank you

You need a vars (a pointer to an array of values), but Equity is a var (just one value).

So you need to feed the MaxVal function a vars of Equity, using series(), so that MaxVal can read an array of values.

That's really helpful, thank you!

Is there anyway of getting the same result without using MaxVal?

The reason I ask is I noticed that I need to make the period a huge value to store the maximum equity otherwise it can decrease in value.

HH() / LL() maybe?

Looks like HH is for price but I'll try this with the Equity value. Thank you!

For equity it will not work, didn't read it all.
Maybe you use maxVal on a static var.

Max value for last 48 hours and put it into a static var.
