Computer Associates' has a point with that persistent commercial. If we were to realistically stop and account for our significant investment in trading software, lease fees and so forth, we would be surprised to notice that on (estimated) average over $600 monthly or $7,200 yearly. by contrast, one of the most robust systems, Esignal with all its extentions and tie-ins to a number of broker execution platforms is only $395 monthly. by contrast, RealTick with its custom indicators and imbalance indicators and multi-charting/multi-timeframe capabilities is equally priced at/around $395 monthly. Whether or not your volume allows for reimbursement for monthly fees, being charged $400 monthly as well as other custom market-data-vendor fees also applies to this calculation...
