Multi time frame Min of last 20 bars

[nigeleyre]

Hello,

I'm using a multi time frame and want to find the MIN of the last 20 bars starting from 10 bars back. I have tried the below but this is obviously not correct, can anyone give me the correct syntax please?

minn15 = MIN(Close(BarsArray[1],20)[10]));

I get the error Close is a property but is used like a method

Thanks.

Try: MIN(Closes[1], 20)[10]
