would think it would be easy.My biggest request would be the ability to multiply, So we can say Buy @ 95% of current value, Sell at 103%
Just FYI, when you say "ability to multiply...buy...sell", you appear to be requesting a trading platform, not a simple ticker. Building a full multi-exchange client with the capacity to perform secure transactions is *much* more difficult than building a simple ticker. A ticker is easy -- a multi-exchange trading platform...not so much.
