So you ghost write for the people you think are worthless in the market....Every single tool uses past information to predict future price action, call it what every you want. There are those who trade and those who simply write about all day long year in and year out...
I disagree about every tool using past information. Take company forecasts for example or macro economic forecasts for that matter. While i agree, only the past exists, if you use forecasts -- are you using the past?
