Deribit options Delta is a dynamic hedging strategy

Deribit options Delta is a dynamic hedging strategy

The strategy of this FMZ quantification is:Deribit options Delta is a dynamic hedging strategyThis is known as the dynamic delta hedging (DDH) strategy.

In order to learn options trading, we usually need to master these concepts:

• Option pricing model, B-S model, option price is determined by the price fluctuation of the item, the leverage fluctuation, the expiry remaining time fluctuation, the implied volatility fluctuation, the risk-free interest rate fluctuation.

• The risk of options:

  • The directional risk of the Delta option. If the Delta is +0.50, the option is treated as a 0.50 spot if the gain or loss on the price falls.
  • The acceleration of risk in the direction of the Gamma curve. For example, a bullish option, due to the action of Gamma, starts from the price of the index at the price of the trading position, and the Delta will rise gradually from +0.50 to +1.00 as the price rises.
  • Theta leverage time leverage. When you buy an option, if the quoted price does not move, you will pay the fee indicated in the theta amount ("Deribit in USD") every day. When you sell the option, if the price of the option does not move, you will receive the fee indicated in the Theta amount every other day.
  • Vega Curve Volatility cap.  When you buy an option, the Vega is positive, i.e. it has a high volatility.  When the implied volatility increases, you will gain at the Vega cap.  Conversely, when you sell the option, the implied volatility decreases, you will gain.

DDH explains its strategy:

• The DDH Principle explained The risk neutrality of the direction of trade is achieved by aligning the options and futures deltas. Since the options deltas are variable and follow the price changes of the indices, the futures and spot deltas are constant. After holding options contract positions and matching them with a futures hedge delta, the overall delta will again be unbalanced as the price of the underlying changes. A continuous dynamic hedge delta is required for a combination of options and futures positions.

  For example: When we buy a bear option, we hold a bear position; this is when we need to hedge the option delta with a blank futures to achieve overall delta neutrality ((0 or close to 0)). We don't take into account the remaining time of the option contract, the volatility rate and other factors. The first scenario: The price of the underlying asset rises, the delta of the option portion increases, the overall delta moves to the positive number, the futures need to be hedged again, and the opening of a portion of the blank position continues to be a blank futures, bringing the overall delta back into balance. (Before rebalancing, the delta of the option is large, the delta of the futures is relatively small, and the marginal gains of the options outweigh the marginal losses of the contract blank, and the entire portfolio gains)

  Situation two: Commodity prices fell, the options part of the delta decreased, the overall delta moved negative, and some of the futures holdings of the blank heads of the equation leveled off, bringing the overall delta back into balance. (Before rebalancing again, the delta of the option is small, the delta of the futures is relatively large, and the marginal loss of the options is less than the marginal gain of the contract blank, and the entire portfolio will still have gains)

  So ideally, a fall in the price of a commodity will bring a profit, as long as the market is volatile.

  However, there are also factors to consider: time value, transaction costs, etc.

  So I quote from the explanation of the cow:

  Gamma Scalping 的关注点并不是delta，dynamic delta hedging 只是过程中规避underlying价格风险的一种做法而已。
  Gamma Scalping 关注的是Alpha，此Alpha不是选股的Alpha，这里的Alpha = Gamma/Theta也就是单位Theta的时间损耗换来多少Gamma，
  这个是关注的点。可以构建出上涨和下跌都浮盈的组合，但一定伴随时间损耗，那问题就在于性价比了。
