What these levels mean
Call resistance (call wall) is the strike with the largest net gamma exposure. Put support (put wall) is the strike with the most negative net gamma exposure. Call resistance is also the gamma wall, the strike with the largest gamma times open interest, puts counted as negative, so the two names mark one strike.
The HVL is the strike where the running sum of net gamma exposure, added up from the lowest strike, is lowest. Above the HVL, net gamma exposure is positive on balance, which may mean smaller moves. Below it, net gamma exposure is negative on balance, which may mean larger moves. The 1-day range, the expected move, is the close plus or minus a one-day move at IV30, the implied volatility of the listed expiry closest to 30 trading days out.
