From reading it to trading it

The concepts in these articles — gamma, the walls, expected move — are exactly what NoVo maps live on SPY, QQQ and IWM, with a live streaming map.

The same mechanic runs in crypto, on a faster clock: options there expire at 08:00 UTC every day, so the pin repeats 365 times a year instead of twelve. NoVo draws that map too — gamma by strike, the walls and the flip across crypto-native and US-listed books — in the Crypto Market Map, and the BTC and ETH gamma read is free.
