I have started trading FX - something I never thought I would do. But I really do need stops - the mental stops just didn't work, no surprises there I guess!
Today had a big "spike" - but it seems getting out at your SL is no problem - there is just ton's of liquidity.
And just to reiterate - it's not so much the spike that's the problem - it's having the SL trigger, but with no liquidity, only getting filled far from the original SL. That's was my problem.
If there's no liquidity for one currency pair, then try another? Different pairs have different liquidity at different times.
