What Is A Golden Sweep Option?

A Golden Sweep Option (GSO) is popularized by the folks at Flowalgo and it is basically a very large order that hits the market and takes all or most the inventory/offers at once. This is usually a very high probability signal given the aggressive stance of the trader(s) behind it. 

These orders can be both bullish or bearish not only based on whether Puts or Calls were bought but also based on whether the sweep was on the Call or Put side.

In the example below, just take note of the characteristics that make this a Golden Sweep:

1. Sweep designation
2. Large volume vs Open interest
3. Askside
