No offense to the OP. But are you serious? Is this whole thread a big joke?
You plan on trading for a living with only 75k and you are using brokers like Scottrade?
Some of you say 75k is more than enough to trade with or even 45k. Honestly, how many professional traders do you know that trade that small of an account and make 6 figures? I know ZERO. Yes, maybe a retail guy got lucky 1 year with 45k, but consistent for 3+ years is a rarity. Next comes Scottrade, please do some research on finding a better broker. You must not care about execution speed or commissions. Do you know how much you would save in commissions if you made 100k and you were trading with a real discount broker vs Scottrade.
I am actually shocked to read people like this believe they can trade for a living, (ie- the guy just shorted a stock for the first time ever and his wife is getting excited about the business).
There are so many red flags, I just keep shaking my head.
My suggestion- Go to IB, Keep your day job or part time job. Never use borrowed money like an insurance or home LOAN to trade, and be prepared to lose all of your money you have in the market for when your support and resistance strategy stops working.
