Quote from Rob Johnson:
How did you add the buy/sell signals at the bottom of your pic?
Entry is signalled when the two calculations agree, provided that supporting one-second algorithms on tape internals caculable only on a mini-Cray concur.
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.
