I'm trying to trade the oil future, so I'd like to get a oil future charts first? The only one I know is E*signal for now, and it's very expensive. I appreciate if anyone can recommend me some good software or websites.
Who is your broker, most brokers offer some kind of charts? Take a look at Ninja Trader/Zenfire, you can use their charts for free.
the least expensive way is to use ninjatrader software, it is free and subscribe to barchart.com for the data feed for $110 actually, i can't say it is definitely the cheapest, but it is the cheapest i have found.
I have an account with Optionsxpress. They provide Real Time Future charts if you have an account. Their "Flex Charts" are real time streaming on all stocks, options, and futures.
Trading's a business & businesses have expenses. My choice is DTN Prophet X. It's not inexpensive, per se, but it's the best I've found for trading CL. $.20 on a 1-lot per month should pay for it. GL!
