EURUSD Carnage day

If you had a bad day trading the EURUSD you are not the only one. Institutional traders are trying to get your cash that you made trading on Friday. as we know the fed announced the rate hike which made the Dollar come up and the Euro tank. That being said we won't know if this is the case until we are in right? Well There is a way to stop from losing and that is the 3 trades rule. If you are wrong more than 3 times you should just be done from today.
