trading systems and signals advice

hi,

Got some questions, please answer:

1/. What do you think are best indicators for short term trading, as in t1, m1, m5, m15, m30?

2/. now are a plethora of systems out there, ninjatrader, multicharts, trade station, metatrader etc, which would you recommend and most reliable pairing with which broker? for both auto and manual

3/ any good signal providers you can recommend?

I used metatrader a few years ago and it was so bad i gave up, now wanting to get back into forex trading as i think it is a good time, but this time with a reliable system and broker....

I see metatrader looks better these days, but what are thoughts on latest version ?

thanks
