Disadvantages of Exchange Test Sessions- the organisational overhead is deceptively high, unless you block book testing sessions for extended periods. Some exchanges require booking a week in advance, which can be highly disruptive to the testing cycle - there is usually little or no control over who else is testing that day and how they are testing, what the market's behaviour will be. In some cases you may find your orders filled when you don't want them, or have to trade against yourself. - considering line cost, session charges, hosting and maintenance of exchange gateways and general management time, exchange test sessions can work out to be expensive. - test sessions are generally low volume (unless the exchange arranges volume testing) - trading periods are short; if you miss the opening then you might waste an entire day of testing. In any case, you may get only one or two opportunities to test your systems for specific market transitions.
Aren't exchange test sessions more authentic?- yes, in terms of communications protocols and the finer points of exchange behaviour, exchange testing sessions should be as close as you can get to the 'real thing' ExoSim™ mimics exchange behaviour as closely as possible. We even let you simulate the propagation delay to the exchange, so you can predict the effect of slower or quicker line speeds.
