[racevedoz]

Hello racevedoz,

Thank you for writing in and welcome to the NinjaScript Support Forum!

I'm not quite sure what you mean about checking if the fast limit crosses above or below the slow limit. These two items are parameters that would be passed to the MAMA indicator itself. The indicator plots two lines: the Fama line and the default MAMA line. Are you asking how to check if the Fama line is crossing above/below the MAMA line?

Are you referring to the Strategy Wizard or are you coding this manually through the NinjaScript Editor?

Yes, I'm referring to the strategy wizard

This is my condition 1 , Cross Above(Mama(0.5, Myinput 0).Fama, Mama(Myinput0,.005) Fama,1)

Hello racevedoz,

If you wish to check if the Fama line is crossing above or below the MAMA line, follow the steps below:

• In the Condition Builder, select the MAMA indicator in the left column
• Enter the parameters to your liking. Ensure that the Fama plot is selected
• Select CrossAbove (or CrossBelow) as your comparison in the middle column
• Select the MAMA indicator in the right column, set your parameters, and select MAMA as the plot

If you wish to check if the MAMA line is crossing above/below the Fama line instead, select MAMA for the first column's plot and Fama for the last column's plot.

Please, let us know if we may be of further assistance.
