CBOE Global (CBOE) shares of the options exchange are showing great relative strength as a bull flag forms between 200-210 and closed strong +2.5% Tuesday with market volatility up ticking, often a benefit to the exchanges. CBOE also has seen options volumes growing quarter after quarter and likely should benefit from the newly listed Bitcoin ETF options that are coming. CBOE can breakout above 210 and run up to the 220 level which would be a new all time high. CBOE still has 2300x January $200 calls in open interest from buyers last winter.
