Firstly, you will have to collect with yourself that many funds which won't get you in any financial troubles in case you lose all your funded money.
Secondly, choose a decent broker- motilal, zerodha, ect. All good brokers have their personal advisers who will manage you portfolio on your behalf.
Thirdly, you have to stay patient and emotionally strong so that you are able to bear any unwanted fluctuations. Keep a track of your portfolio and if you are booking losses out of your limits, you better quit and don't get stuck, risking your other assets.
