The charting package is eSignal. It allows you to add to the basic chart so-called "studies" which are home-grown codes in their scripted language EFS. You can highlight the code results in colors as you desire. The exaggerated Cray aspect is that with a fast large memory computer you can run some pretty impressive codes at tick rates.
Over ten years. It is overkill and too pricy for the straight-forward kind of charting you seem to do. It is best if what you need is clean, low-latency unaggregated tick data and the ability to process it using your own codes. People here tell me NinjaTrader is better, though. I have stuck with eSignal out of reluctance to learn to code differently.
