Loss profit potential.

Yesterday, I lost some profit potential because I didn't follow my rules for my strategy I just set my profit limit a bit earlier which I shouldn't have. The 3 pairs Eur/usd, usd/chf, and gbp/usd trended much farther than I anticipated and if I followed my rules then I would've made alot more profit.

Has anybody did this before?

Forgive my phrasing, if not correct. Hindsight is 20/20. If you second guess yourself you're handipaping yourself from step one. And again, it's only my experience, but a sound money management system that's ound is the first and most important rule in trading.

Yet, I'm a newbie, so what do I know?

NeoEx is right.. it may be due to hindsight that you're saying those "should haves"..
That's why it's important for you to have rules so that you don't focus on what happens because anything can happen..

Learn from the trade... There's more fish in the ocean..

Just my 2 cents though...

Oh yeah, you're asking if anybody did it before? Yup... I'm sure there are a lot, but it shouldn't encourage you to repeat it again..
As for me? Hmmmm... I can't seem to remember... hehehe...
