Income tax

Hello! In Brazil it's applied 15% tax on the profits of a trade, in fact it as bit more complicated than that, but... Is there a way of applying 15% tax on a profitable trade? Thanks

So far only post festum, by analyzing trade data in stats._trades:

stats = bt.run(...)

trades_pl = stats._trades['PnL']
profitable_trades = trades_pl[trades_pl > 0]
profits = profitable_trades.sum()
tax = .15 * profits
...

I see, but I would like the profits to be decreased after a trade, since this tax is paid every month. If not, the simulation will reinvest money that it shouldn't have.
