The gamma ex of ETH and SOL shows positive gamma resistance above.

The resistance for ETH is clearly at 1800; once broken, it will be smooth sailing.

The resistance for SOL is at 160, but there is significant positive gamma resistance from 150 to 160 and above, making it difficult to push higher in the short term. Therefore, SOL is more suitable for building a selling strategy.

Now, let's talk about the stablecoin PAXG. Its gamma ex shows a typical narrow oscillation pattern. The selling strategy may be counterproductive due to low volatility, while the buying strategy has little profit space due to the narrow positive gamma surrounding it. Therefore, gold options are relatively unappealing in the short term and are more suitable for long-term spot trading. After all, in the long run, gold is expected to reach 4000.
