Gamma Exposure

18 lut

Overview:
Gamma is part of the second order of greeks which measure the sensitivity of first order greeks (Delta) to changes in factors of the underlying. Using Gamma, traders can see the potential delta hedging activity by market makers. If market makers are long gamma, they will be buying as price decreases and selling as price increases, which acts as a stabilizing factor on the market. If they are short gamma, they are buying as price increases and selling as price decreases, which can further intensify volatility.

How it works/Calculations:
This indicator will bring the data from an outside source and will calculate Gamma from the Black-Scholes equation. Will take all the open contracts for the underlying and calculate Gamma exposure. A few assumptions will be made that may or may not be true, like making the assumptions that all open contracts were sold by the market maker. Although not perfect, will give an idea of where the market maker will be since the majority will be done by them.
The impact that Gamma has is dependent on different factors, such as open interest, time expiry, and volatility. The more open interest is at a strike that has near- term expiration date, the more likely is that the Gamma exposure will have an impact on the market. Gamma will work as a magnet and pins depending on strong levels.
In the settings, you can choose to see both calls and put Gamma levels or just see the delta, meaning the difference between the calls and the puts. Since this is based on open Interest of the options contracts and those update once a day, this indicator will update once a day as well to give the most current values.

How to use:
You should not be using this indicator for entries or stop. This indicator will help you see where there are possible levels that will serve as magnets or rejections or where price can be pinned.

Pitfalls:
Gamma is one of the second order greeks, there are other greeks that can also affect movement by the market makers. Time to expiry, volatility and open interest impact gamma. We are calculating all open interest as the market maker being the originator of it. Large and elevated exposure in groups of strikes is more likely to be significant than individual smaller strikes.

Disclaimer:
This is still an indicator that in no way should be used alone.
