Was this real money? I guess 300 shares of TSLA would be the outer limits of the daytrade buying power in a $25Kish account.... but man if this was real money...you are friggin nuts to even consider 300 shares of TSLA in a 25K account.
Look I don't know what method you've learned... but just going by your post... its not going to work trading TSLA. First of all, you entered at $303.50 with a stop at $305.01... even if you are 100% right in the directional call, the bid/ask spread on TSLA can reach $1.50 (or damn close) in a blink. That close of a stop will be triggered (on TSLA) on a day when its in a flat-line coma, let alone 9:40 AM on a Friday.
So you go in with 300 shares.... and 5 trades later (paints on the tape) someone buys 100 shares at $305.10 as it moved up a bit and the spread widened..... the next offer on the book is $305.80... which is where you just filled. In this example you just lost $690.... damn near 3% of your account...and you could have been 1000% correct in that TSLA was heading down. 5 minutes later it could easily be $302 on the offer. But you're out and you lost.
I'm not telling you to throw in the towel, but man don't try cutting your teeth day-trading trying to scalp TSLA. Its a beast unto its own and you are no more than a wounded bleeding guppy swimming with sharks. TSLA loves the "news" trade. It takes people money on "news". Both long and short. Never trade TSLA intraday based on news.
Now that I said all that... while writing this I thought about it... and I am being dead serious here..... maybe
you should cut your teeth trading TSLA. Real money. BUT... only use 10 or 15 shares. IB commission is like $0.35 tops, less if you add liquidity, but don't even worry about that, its tuition.
Why do I say this....because I already have a read on your personality. At this point in the game its not about how much you make, its about learning. So what if you only make $10 or $15 a trade; or lose that much. What you want to see is the color green on your daily balance. Period. Not the amount. The color. The sim doesn't get it, its useless for your style. You'll never learn on the sim.
Use real money with real trades. Try it for a week. Forget about trying to make a few $100/day for now. Don't look at it like that. Its not your goal. Only trade TSLA.
BUT USE 10 SHARE LOTS. Consider a $20 win a MAJOR accomplishment, because it is and you should. If you can do this.... ie master TSLA... with a green balance at the EOD... you will be able to trade any other stock out there successfully and with size. I can't think of a more formidable foe for day-trading stocks than TSLA. Its the best and hardest to beat. And the action is there, everyday. Its never a sleeper.
You wanna be the best... then you train against the best. The only way you are gonna learn is getting in that ring. No mentor, no sims, no YouTubes. Get in the ring. 10 share lots buddy. As many trades as you want. Let me see you be green at the EOD 3 days in a row fighting TSLA.
G/L my friend, I hope you do this.
