Can I trade using my mother's demat account to reduce STCG tax?

Can I trade using my mother's demat account to reduce STCG tax? I’m already in the 15% income-tax bracket and have recently started equity swing trading. If I transfer my money to my mother's bank account, she then puts that money into her demat/trading account, but I personally do all the trading and investment decisions, who is liable to pay the tax on the STCG? My mother has little/no other income, so would her ₹4 lakh basic exemption/rebate apply to these gains? Or would the income still be considered mine, since the money originally belongs to me and I’m the one actually doing the trading?
