Same bar order execution

[valentin]

I have trading signals for each day, telling me whether to buy hold or sell. According to my current understanding by default the platform executes on the next bar - which in my case is the next day.
A hacky way to solve this would be – I assume to shift all signals "up" one day in my CSV. This would be not suitable for a live strategy.
How can I tell backtrader to execute either on opening or on the close price of the same bar/day I am currently looking at?
I looked at the cheat-on-options, but not sure if this is the solution.
Thanks

Could you please elaborate a bit?

Do you have them? Are they generated with the data?

I don't know where your understanding has come from. Order execution is described in the docs. It has nothing to do with default, it has to do with order execution type. Docs - Order Management and Execution

Things work as described for a good reason, to be as accurate as possible with backtesting, given the usual inherent limitations the data has, when compared to live action.

Neither can I know, given the lack of actual information. But the name cheat-on-xxxx was chosen for good reasons.

Apparently you already read the pertinent docs, what else would you be expecting?

Thank you. Your hints were enough to find a solution for now.
For testing I simply shift the signal simply up a row. For live purposes I will find another way
