Read the customer indicator value

[adrianyuen]

I'm a newbie to Backtrader and just developed my first custom indicator (I mainly follow the samples at https://community.backtrader.com/topic/2145/full-example-of-custom-indicator/5)

However, when I try to compare indicator values, e.g. lazy is my custom indicator, and I try to compare the values of itself one units ago, i.e.

    self.lazy(-1)>self.lazy(0)

I got the following error message:

bool should return bool, returned LineOwnOperation

I know the custom indicator is actually a line object. How can I get the value of it?

I think you are using wrong brackets. Have a look at delayed indexing. If you are doing this in next section use square brackets. Its all guess as information given is no enough to debug.

Thank you, rajanprabu. You're right, I'm using a wrong bracket...
