Off-the-shelf algo trading systems are perfect for traders looking for an easy to use and affordable automated trading solution. You’ll have peace of mind knowing the software is tried and tested, and support is always available if you need it. Your auto trading solution can be as custom as you want it to be, but increased customization typically comes with trade-offs in time, effort, cost, support, and maintenance.
As a general rule, the more custom your solution (writing directly to the exchange), the more time, expense, and effort will be required to set up and maintain your system. But the potential upside is what makes the customizable nature of blackbox trading such an attractive option for professional traders.
