Don't know about others .. but Imho if you are daytrading without live data, you are pretty much trading blind in this face paced environment. The primary reason is because you would be missing out on the reactions to quick entry and exit signals from candles/bars across various timeframes which can signal small windows of opportunities for entries and exits ( could be seconds) that delayed charts can't substitute . This can often be the difference between a large profit and a substantial loss. Even for those doing well without live data, imo they may be able to perform alot better with it if interpreted correctly.
From memory it is only about 8 trades p/m for free access to Commsec IRESS live data (or $82.50 if less ) ,so even if you are planning daytrade a few days a month , this is easily achievable.
