Metatrader has an excellent programming platform, for writing your own technical indicators and building automated trading.
Problem is: don't do it.
I agree with the others.
As someone that has spent years trading stocks futures and warrants(a kind of option)...
And as someone who has read roughly a 100 books on trading, markets, investing, predictive finance...
And as someone who spent 5 years trying to write automated technical trader bots....
(And sought out and paid trading "experts" to learn from them in person)
I'm telling you: Don't do it.
The markets are pretty efficient.
Making money by trading is very very hard work.
You have significantly better odds with buying and holding high growth blue chips.
I know you want to trade.
But reconsider: at least paper trade for a year - this will open your eyes - and prove whether you are serious about becoming a professional, or just a dabbler about to lose a painful amount of money.
