Confused - How to find out, "am I LONG or am I Short?"...only: "Yes you are!" ?

TraderOnes

Hey guys,
it is so basic but a solution is not researchable for me...
May I ask: How to find out, if my actual position is LONG or Short within "next" of the strategy-class?

Every Quickstart-example has this Checkout:

        # Check if we are in the market
        if not self.position:

Perfect, also possible to check position.size, position.price, len(self.position).
But not if it is SELL or BUY?

"notify_order" has order-Methods:

isbuy(): returns bool indicating if the order buys
issell(): returns bool indicating if the order sells

But how to use them within "next" of the strategy-class?

Should look like this somehow

# Check if we are in the market
        if not self.position:

            if buy_signal:
                self.order = self.buy()

            if self.sell_signial:
                self.order = self.sell()
        else:
            if bt.And(we-are-long, self.sell_signial):
                self.order = self.close()
            
            if bt.And(we-are-short, self.buy_signial):
                self.order = self.close()

But how to define "we-are-short", "we-are-long" ???
I tried alot, but only error-messages.
Any ideas?

check for position size:

if self.position.size < 0:
    # you are short
elif self.position.size > 0:
    # you are long
else:
     # no open position

hey yes,
Works!
Sorry to mention: I printed out position.size to see, if it is going negativ...but it was allways positive, Long and Short.

But anyway...somehow it is not...maybe I was looking wrong, or formating-error.

Now it works with no error.
Thanks so much for quick reply!
