TVO and the Heat Gauge were primarily designed as systems to trade the markets minus the price charts and the all-day vigilance. On Thursday’s close, at 4500 feet near the summit of Mt Garfield (the top is the only place where your smart phone can get any kind of service), we exited our SPY calls from Monday for a 30% gain… With a simple and effective system, trading doesn’t have to stand between you and a lifelong passion. Volume fell in the session overall, and although the Nasdaq squeezed in a bit of accumulation, SPY doesn’t seem quite ready get on the board the train. -MDLogin. Not a Member? Join us.
