Quote from ralph00:
It really depends how you trade. I have found such focus on day-to-day performance to be profoundly negative for my results over the years.
On my twitter stream today, I couldn't believe all the chatter about the "move in the euro", "the short squeeze in the euro", ... what have you. The fucking thing was up a handful of pips and just took back some silly zero volume action from the last couple days of the year. Nothing more than a random wiggle from where I sit, and folks couldn't stop talking about it.
"You never count your money while you're sittin at the table, there'll be time enough for countin', when the dealing's done."
You're talking about following intraday market chatter, whereas he is talking about end of day checks of your P&L - two totally different things.
You have to check your statements daily anyway, to identify position errors, looming expiries, large moves in your open positions, and so on, so you are going to notice your P&L regardless. Might as well build sound records and performance monitoring while you are at it.
Like he said - you can't know what you are doing right and wrong, if you aren't looking at what is helping or hindering your performance. How can you improve if you aren't sure whether it was Euros, soybeans, or some Canadian junior miner that most impacted your performance recently? I can understand not looking daily at long-only, cash-only investment positions (things you would hold for 1 year+), but surely with futures and shorter-term plays it requires frequent attention?
