A winning Strategy

[MightyMaxSaviorOfTheUniverse]

Hello

This isn't really an issue with this program and more of a financial crises.

I use the mean, mode, average, highs and lows to determine the direction of any particular stock, and even though this method is nearly 25% accurate I want more

I also use bell curves and that helps quite a bit but what other strategies can be used to better predict the stock, or what other means are there to make a winning code?

PS: This new method of placing bets seems to be nearly perfect, I've been trading for a few days and not once have I received that old NONE return error. I'm still getting, 'asset isn't available' and timing issues.
