Traders have found out that many automated E-mini trading systems have not been able to cope with this extreme volatility very well. Some traders have simply turned the systems off until volatility subsides whilst others have been rushing to modify code so that entries and exit levels and risks are more proportional to current volatility. It may also be a good time to look at the Micro contracts which are just 10% of the size of the mini S&P. If we do switch to trading the Micro’s we should still be taking our trading signals off of the E-mini contracts. With most trading platforms it is easy to set it up so the system is still monitoring the E-mini contract but actually places the trades on the Micro contract.
