Why not build a business around a problem I'm passionate about solving?

Because there is no shortage of unverified technical analysis tools out there?

    Those who can --- trade.

    Those who can't --- sell tools.

Good luck. You'll be an upstart in a field that is already fairly saturated with well entrenched players.

If you really have something of merit, my best advice would be to look at becoming a 3rd party add-on provider for one of these existing platforms like ninjatrader.
