Hi Samuel,
During important news it is quite possible for the price of an asset to drop more than 5% of account balance if lot size is too large. This could then cause FTMO account to fail test. If the lot size is made quite low to avoid a 5% account balance drawdown then the FTMO account may not reach 10% profit by end of its testing period. I understand what Petko that over the long term the swings caused by important news events will cancel each other, however, when trying to use EA’s with FTMO this logic does not apply. The alternative is to either manually close all trades before an event, if I can remember to do so and I am at my computer which I may not be able to do, or to find an MT4 script I can add to each EA code. I am just trying to figure out how to handle this potential problem when trying to pass the FTMO testing period.
