regarding the 89sma using the 1 minute charts and the "session begins" at 9:30est.
seems that the 89sma doesn't have enough bars to be accurate. for example: 8:30est "session begins" will have the 89sma at a different level which makes sense so i would assume that a chart would need to be started at 89minutes before it would be accurate or 8:01est.
how would i go about using a chart that starts at 8:01est and a strategy to start at 9:30est?
