What is important is what is the average stoploss your trades timeframe requires in Reliance Infra. If it is 1.54 points or less, then you can trade one Relinfra contract in Rs 1,00,000 capital as the risk per trade will be 2 %. If you are taking 1% rish per trade in intraday then your average stoploss should be less than 0.75 points...if that is not possible then one cannot trade 1 contract of Relinfra in Rs 1,00,000 capital.
