Limit Order Duplicate Help

Hi All, I'm working on an algo that sells VXX and SPY options (So far I've only worked on VXX). When I enter my Limit Order to sell VXX calls I'm seeing two duplicate orders, so twice the amount of options i'd like to sell. Has anyone experienced this?

Hi Steph,

The reason the algorithm submits two orders for VXX is because of this logic:

for symbol in self.symbols:
...
for chain in slice.OptionChains:
if str(chain.Key) == "?VXX":
...
# submit order

The if condition is called 4 times and is True twice.

See the attached backtest for a working solution. Note that we do not need to use the `self` keyword for local variables.

Best,
Derek Melchin
