I consider the margin interest rate very cheap, the interest is about 66 cents per day per $3000 borrowed or .022% daily interest (that's loan amount x .00022). You're only charged interest if your margin purchasing power is invested in a stock, so if you sell your stock you are no longer charged the interest. For me, that's practically free money because I average 4% to 10% gain per trade per day. I make anywhere from 2 to 6 trades per week. About 25% of my picks result in a loss, but the gains heavy outweigh the losses. There is A LOT of research involved to find the gems, and I admit yes it is stressful but it's kind of like Christmas morning every day you wake up and Christmas eve when you go to sleep because the stocks I pick will either take a big jump or big loss the very morning of the opening bell. It's extremely exciting. Now, I also admit that I've only been trading during this recent bull market. I have no idea how my strategy would work in a bear market. I do not consider myself as a day trader, because day traders often make dozens if not hundreds of trades per day. I buy a stock and hang on to it for 7 or less trading hours.
