objects - i.e. you can just do q.ask_price
to get the price from the received Quote
s.
In your quote_callback
function you get every Quote
object as an argument. So, if you always only want to access the last received Quote
object which has symbol
= "HB"
, you could define a global dictionary named e.g. quotes
which will contain one key == symbol and value == last Quote
with that symbol per symbol type.
Now, in get_quote
you can use a simple dictionary lookup for the desired key in the quotes
dictionary. In the end, you need to repeatedly call get_quote
until a quote object with the desired symbol value is received. The whole code could look like this:
