Single timeframe works fine for me.
Isn't all about price anyway? Does the market know or care if price moved a point on a tick or a 15 minute chart? On one chart, a bar could be red and on another its green. All the information of the market is in all charts regardless of timeframe.
ZAL, is that rate for all TradeMaven accounts or just those that join the service?
Also, what do you mean by "throttled" data? Is Ninja/Zenfire throttled or un-throttled and do you offer that?
