Mainly, at any moment with a priori known market volatility, the current price and LP GEX at that price determine LVR (or LVH). This is a very interesting insight Now you can measure the level of "strength" a MM has and how it can "influence" the price of the underlying asset (remember: we are not talking about market manipulation we are talking about how many securities the MMs need to buy or sell to be fully hedge.. but, sometimes that number is so big that, at the end, they affect the price - So: are you saying those mini rallies at the end of the day could be due to this??

But should the market drop into negative gamma territory, expect fireworks. And this largely depends on how "the street" is positioned. And this number is the Delta Exposure in dollar terms for this trade. This point represents the current spot gamma exposure and occurs at around -$19Bn. Gamma Exposure for Liquidity Providers Leads to Loss-Versus-Rebalancing, This site requires JavaScript to run correctly. So that's why we have those positive and negative signs in our formulas simple, right??? For more on TradFi MM GEX, see the GEX whitepaper. Open Interest No worries, the reason behind that square is the following: If Gamma * Open Interest * Multiplier * Spot price will give me the GEX for 1$ move change in price of the underlying asset (mainly because gamma is the change of delta per 1$ price move in the underlying asset); how much will it be the GEX if I have Price * 1% move?? As a result, they have to buy additional securities when prices are rising, and sell when prices are falling to help to ensure their positions are neutral even as the value of the underlying changes. At the chosen point, the curvature (really, the second derivative) is referred to as the Greek letter Gamma . How To Calculate Gamma Exposure and Zero Gamma Level. market microstructure - Gamma Imbalance / Exposure - Quantitative This level tells you the strike price that separates the negative GEX area from the positive GEX area (others call this level as volatility trigger but it is exacly the same is when things turn negative or when things turn positive and a point where we can "expect" an increase or a decrease in volatility). (Geometric Brownian Motion). But, since a long position on the asset has zero , the MM now has nonzero exposure, and they must actively manage their long position to maintain -neutrality. The call and put both have positive , and the covered call has negative . Follow us on Twitter at @primitiveRnD for more content and see our GitHub for open source code and docs. Our research emphasizes improved UX for DeFi. As prices rise, the market maker must add positive exposure thereby adding "fuel to the fire" by buying more. Well, if we only anlayze the nature of the sign: yes it is simple (basically you have to know how Gamma behaves when you have a long or short position in an option); however, the most important question is not whether the signs make sense, but whether the assumption is correct; and in order for us to answer this, we need to look at the shape of the volatility smile/smirk of an index. So, if the market is buying puts and selling calls, the MMs must be selling puts and buying calls (and this is why the MMs has positive gamma in their call positions and negative gamma in their put positions).

Pandas dataframe must contain "RIC", "Trade Date", "Open Interest", and "Implied Volatility" fields to calculate time series of estimated daily market maker gamma exposure, "CBOE_GEX" is the simplest to use. Can we quantify the GEX for DEXs that are combined with borrowing/lending protocols? We value education, free information and sovereignty. So I am wondering whether there is a way to get a more robust estimate.. This post compares DeFi LPs and TradFi MMs and connects the dots between LVR and GEX.

Market makers (MMs) are market participants that get paid to add liquidity to markets. Notice that both a call and covered call have positive slopes for all prices, therefore positive . So, in general we will need to use the following formulas for us to be able to calculate the Gamma Exposure at any strike from a MM point of view: GEX (for call options) = +1 * Gamma * Open Interest * Multiplier * Spot Price, GEX (for put options) = -1 * Gamma * Open Interest * Multiplier * Spot Price. ok, so that would mean making the opposite assumption.. thanks! Most anticipated earnings releases for the week beginning Expected Moves this week. All in all gamma flip or volatility trigger points are derived from an estimation how market makers are . We can realize V(S)=g(S)=x*(S). It's better to normalize the MAD variances for GEX 67%, 95% and 99.7% intervals, use MAD then 1.46 to normalize. This is a very interesting insight Now you can measure the level of "strength" a MM has and how it can "influence" the price of the underlying asset (remember: we are not talking about market manipulation we are talking about how many securities the MMs need to buy or sell to be fully hedge.. but, sometimes that number is so big that, at the end, they affect the price -, If you want to have access to the code that generates all this analysis (and more), use the following. Still, though, we did not cross below our trigger line, ZERO, for a 51% at a trough or 13 % before one success rate ! Free Gamma Exposure Chart | SpotGamma So if we download (via Yahoo Finance or CBOE) the SPX, SPY and XSP option chain and apply the above formula to each strike and then add it all up, we can calculate the GEX for the SP500 (or at least it will be a good estimate according to our assumptions).

LVR was hinted at in an earlier paper Replicating Monotonic Payoffs Without Oracles (preprint). Well, the result is as follows: You will be able to tell if the current conditions can be better or worse in terms of volatility/GEX scenarios after this week or after this month simply by looking at how the GEX profile collapses or expands. In relation to the sign, there is one assumption that we need to make in order for our model to work properly. As traders, we are always interested in developing and understanding new and persistent market edges. Thus, by managing an LPs GEX, the LP can take back profit from arbitrageurs and keep it for themselves. So, knowing GEX will give you an edge in terms of which strategy can perform better. If, e.g., a market-maker sells a single, 20-delta put contract to an investor, he must then short-sell approximately 20 shares of the underlying stock* in order to (temporarily) neutralize the convexity eQect of the option's gains and losses. This is a standard net gamma curve, using basic assumptions that options liquidity providers are short put options and long calls. This exacerbates market moves and removes liquidity (frequently, when its needed the most). Notice the term in the integrand g(S). This suggests that the market buys puts for protection and sell calls for financing the cost of that protection (which makes sense due to several theories like prospect theory where investors are not risk averse as traditional finance suggests but more loss averse, amongst others). We will be in touch. The nonlinear payoff allows traders to make directional bets and hedge unfavorable price movements. I use Excel Pivot charts and Python to implement a great visual representation of gamma hedging. Thus, by managing an LPs GEX, the LP can take back profit from arbitrageurs and keep it for themselves. If you want to have access to the code that generates all this analysis (and more), use the following link. We test our joint hypothesis using a large panel of equity options that we use to compute a proxy of stock-level gamma imbalance. Is there anything that can stop gamma and its evil plans? prove in. Now, MM trading 101 in terms of risk management. then define Loss-Versus-Holding (LVH), which is the exact definition of impermanent loss: For LPs, we see that LVH is given by taking x_s=x_0, and they show that LVH has variation bounded below by LVR.

Option markets use the (real-and made-up) Greek letters gamma, delta, vega, theta, and rho to quantify each option's economic exposure. To further explore this and other open research topics, visit: studies market design and MEV in the DeFi space. Gamma is directly related to delta and theta: Gamma is the first derivative of delta (with respect to underlying price). SPX-Gamma-Exposure has no bugs, it has no vulnerabilities and it has low support. Of course, gamma is just one of the market forces here, and its impact largely depends on several factors, such as: Time to Expiry The second level is where the Total Gamma Exposure blue line crosses zero. In a future post, Colin will discuss TradFi and DeFi MMs in more depth, as well as CFMM GEX and volatility from it. In Traditional Finance (TradFi), Market Makers (MMs) constantly hedge their Gamma Exposure (GEX) to avoid losses. In this paper, Squeeze Metrics did an amazing job explaining what Gamma Exposure is and its implication in the hedging dynamics of any Market Maker (if you want to read this paper, use the following link and you will be able to download it). According to this resource.. which is the exact definition of impermanent loss: Whats the point of all of this? We discuss how market designers, crypto traders, LPs and quants can build positions to reduce the GEX loss vector. I like to do it assuming a range of prices from -20% to +20% from the current spot price to have a full picture of the GEX profile plus minus 20% of current price level. The optimal amount of .

Click the link we sent to , or click here to sign in. The amount of delta-hedging needed is mainly dependent on this thing called gamma. For CFMMs, computing the LP GEX is not too difficult, and the cumulative GEX for DEXs could prove to be an interesting means for constructing a decentralized volatility oracle. Go to http://www.cboe.com/delayedquote/quote-table-download and enter "SPX" in the ticker box. On an index level, it is generally believed that investors predominantly buy puts for protection and sell calls as part of overwriting strategies.
