Setting exclusive_order = False

[alessiaf12]

What's the rationale behind the exclusive_order parameter when it's set to False in Backtest class? How are the entry and close positions chosen?

I perfectly understand how the parameter works when set to True, however when False is set i cannot understand properly which is the rationale impllied.

Backtest(..., exclusive_orders=True) calls position.close() before opening any new order.

One would leave exclusive_orders=False if they wanted to add to (pyramid) existing positions, e.g.

    def next(self):
        assert self.position.size > 0
        self.buy(size=10)
        # On next iteration, position.size would be +10

Thank you for yout reply.

But it's still not very clear to me. Can I have more information about it? maybe a more datailed example.

An example would be wanting to add to an existing trade. You already have 10 stocks and want to buy another 10.

But with exclusive_orders=True, any new call to Strategy.buy(size=10) would automatically close the prior trade.
