Reading a print

Each row carries time (true exchange time, in ET), symbol, spot, expiry, strike, call/put, fill side, size, price, premium, volume, open interest, implied volatility, and the trade type.

Fill side is the tell. At or above the ask reads green for aggressive buying, and above the ask is the most aggressive of all; at or below the bid reads red for selling. Sentiment combines side and type: call-buying and put-selling read bullish, call-selling and put-buying read bearish. Fill side and sentiment are on Pro and up.
