what to see before buying a trading software and data feeding?

#1
Hello friends,

I want clarification regarding "what to see before buying a trading software and data feeder?"

I had followed some amibroker,metastock,meta trader etc,
but getting dubious and cannot take a decision.

1. I want technical analysis with better graphics,formulae writing, indicator creation/modification,history based analysis,automated buy/sell signals creation,automated sms sending facility. For NSE/FOREX/BSE/ commodities/ currency
2. data feeder :realtime with maximum no delay from NSE/BSE servers.

If any better optioned softwares.

please suggest beyond reality of humane knowledge(purely technical)

sincerely
Suresh Kumar
