This thread highlights what can go wrong when broker platform breaks down. https://www.elitetrader.com/et/threads/trading-technologies-tt-a-career-ending-software.335159/ It can be extremely damaging for day-trading futures scalpers who uses huge leverage. After they placed highly leveraged orders, the platform breaks down leaving their highly leveraged positions meant to be ultra-short term exposed for the rest of the day. It can kill traders if that day happens to be a huge reversal day. Using multiple brokers is a solution for those who have long-term positions but not a solution for these day-trading scalpers. How would elitetraders, especially short-term scalpers, manage this risk?
