I've said it before, I believe broker is key. Reliable execution, good spreads. During the SNB carnage my broker got me out of both Z12 and Z3 relatively unscathed compared to the experience of others, and soon after refunded me the difference between their inital executed prices and actual executed prices, which were in my favour. You can still see the hit in myfxbook account around Jan 15, but my account survived and has kept making money. As a note, I believe I am very conservative with my capital. Consistently have buffer in excess of Z strategies recommendations.
