All segments of the market — be it equity, debt, futures and options, commodities, and more — can be traded without any brokerage charges with a zero balance demat account using a zero brokerage demat account.
If your starting account is $500, you shouldn't make a single trade using more than $100. Making just 5% on each trade will earn you $10 a day, even if you only make ten trades. If one of your trades performs even better than expected, you can celebrate it and resume your disciplined strategy.
The 3 5 7 rule is a risk management strategy in trading that emphasizes limiting risk on each individual trade to 3% of the trading capital, keeping overall exposure to 5% across all trades, and ensuring that winning trades yield at least 7% more profit than losing trades.
Yes, of course you can make $100 a day trading with $100. Just invest $100 to buy a stock that will go up 100% before market closes.
