Hi there. I am new to backtrader and seek for some kind help.

What is the standard way of extracting the previous ten bars' highest close price? I just skimmed the doc but didn't find the standard way. I once tried a brute force for loop method, but the program ran much slower than before...

It seems like self.datas[0].close is not a pandas series, so there seems no convenient way of doing this task.

Any help would be appreciated.
