The backtest run successfully online (a basic template, no holding implemented, checking with debug file).

Objective: testing schedule function, history request, reconstructing pandas structure, applying basic math function( quantile in the exemple) and logging result ( ticker+ last close + quantile 75th).

When testing in local mode i have this runtime error:

Data on local files have been checked with editor edit and BasicTemplate.py. EveryOK.

self.History seems to be the problem but i have no idea.

Help needed...thanks.
