Force the order executed at specific price with certain size

[VincentLee]

I am using other program to simulate trade on stock market(using tick data). And I would like to force the backtrader to execute every order by the trade records(see graph).

For example, when the signal above 1, all-in with open price then sell certain size with open price * (1+rate).
I tried to use backtrader.order.limit to create order, but sometimes it will not execute with right price because of the intern logic of limit order.

I wonder if there is any way to force the order executed at specific price with certain size, something like:

self.buy(price=self.datas[0].open[0], size=1000, exectype=backtrader.Order.Force)

will execute this order next bar without checking open price or any other price.

@vincentlee Backtrader is meant to simulate real life as much as possible. It's decisions will seek the best fill order based up on the available data.
