I'm trying to figure out what the following code needs with double and what it does to the code. Help me understand?

[B]double [/B]value = MAX(High, 20)[0];

Hello jertrade,

Thanks for your post.

In your code example of double value = MAX(High, 20)[0];

The "double" is creating a local variable called value that is the variable type double which is a floating point type number, here is an internet link to the definition of the C# double type: https://docs.microsoft.com/en-us/dot...-numeric-types

The MAX() method will provide the maximum (in this case) of the High data series of the last 20 bars (including the current bar [0]): Reference: https://ninjatrader.com/support/help...aximum_max.htm The maximum value is then assigned to the variable called value.
