Suggest me the best brokerage (low charges) for intraday trading

I'm new to trading, I'm currently learning intraday trading for recent couple of days, I want a best brokerage for intraday trading (I'm going to learn with very low capital like buying 5 shares for 15 rupees and try sell 15.5 rupees and getting 2.5 rupees as a cross profit) I'm going to do it multiple times for learning purpose. During this process,So I need an broker who charges very low for complete buy and sell intraday trading for multiple times (including all taxes like brokerage fee,stt,gst and many more) I used brokerage calculator of many brokers,they gave different net profits,but I need optimal one,So please suggest me the good efficient one with low charges for intraday trading. Thanks in advance✨
