Short answer is yes to everything. It's a broad structure plan subject to your level of skill at analysis and risk tolerance. I started trading this exact setup almost 20 years ago, starting with $5000. I doubled it in 4 days and dropped the original 5000 into swings while continuing to day trade the other. Once I hit $50k (2 months later) I started adjusting to fit my needs. It's a great plan, but it does nothing without technicals and patience for entry/exit. To this day, I still day trade daily and I average 1000-5000 per day trade, sometimes with AAPL, IWM, QQQ, SPY I'll go as high as $25-$30k per trade (much less often though)....just depends on the setup, contract, time of week/month. No matter how many trades/swings/etc. I have on the ledger, I always aim to get $1000-$2000 per day on day trades...,this is my "income."
I used to have 3 trading accounts but have since consolidated to 2. Ultimately, I take X amount over my personal limit I set in my trading account and transfer it to my core portfolio to invest (once a quarter), X amount comes out for income (sometimes monthly).
Point is, it's all about your needs.
