inaccurate trades number

[kfkf9999]

I test a simple strategy, like

if self.data.Close[-1] > self.data.Close[-2]:
    self.buy()
if self.data.Close[-1] < self.data.Close[-2]:
    self.sell()

however, when bt.plot(), Trades(1) showed.

What's happening?

Buy and sell methods, by default, make orders for size equivalent to full free equity (available cash + margin), which fluctuates in time depending on the underlying OHLC values.

You might want to consider passing explicit buy/sell size= parameter.

Alternatively, you should be able to control the explicit closing of trades with trade.close() or position.close().

Thank you! I resolve!

@kernc hello bro!, is the size parameter given in USD terms? I mean, when I see the _trades results I see "-883" (for example). Is that number the size in USD (the quantity of USD I use to open the trade)?

[kernc]

The size= parameter matches Order.size / Trade.size.
