10k to day trading is a sure way to fail.
since it is too tiny, you need margin. when margin is involved, you are under control by the brokage. market is valitle, 20% agversary happens everyday, when you are forced to get out, the market takes your money and smile back: you fool, bet again.
you need very accurate timing, plus you need high rate of judgement correctness. just like walk on a thin steel rope bridge to pass a wide rapid river between two high mountains. you are nervous, one step miss, you are down to the hell. if you have a big account like 1m, 1 contract even 10, 20 contracts of ES, even against you 100points, to you, not hurt at all. but to a 100k account, already cut half. to a 50k account, the account dissapeared. 10k account, just 2 contracts at the most, if use intra-day margin, just 4 contracts, just 50points move, you are gone, so your accuracy must be within 50points. you may say you can put stop loss with 10points, or 5 points, or 3 points, even 1points, that is possible. but when you use tight stop, your chance of being stopped out is greatly increased, the tighter the stop loss, the more the chance to be stopped out. 10 points of ES move is just noises, but to a day trader using high margin or full margin, this whipsaw noise move can kill him in blink of eye.
when you are stopped out and you see teh Mr. market smiles back, you may charge in again, "you want your money back", easily get another blow, you may find yourself your account quicly lost 10%, 20%, 30% value just in several trades. when you want to climb back, it is harder to climb since 50% reduction needs 100% gain!
so with a small account, do day trading is stupid. better find some trending well market, park your money there, ride patiently. for example, if you are in aapl, several years ago, it was just 50bucks, but now it is almost 700bucks stock. lots lots of this kind of story. or QQQ, in 2009, it was 25ish, now it is almost 70.
find the easiest and safest way to make money is the key. day trading a small account is highly risky!
