Trade plan is nothing but money management. We should not take risk of more than 2% of our capital in single trade. Then only we can trade on long run, at least 50 trades if we fails all the trades.
Our entry and exit levels should be near to support and resistance levels respectively or 1:1 risk-reward ratio.
Based on our entry-level and stop loss, we have to calculate the quantity in such a way that our risk should not be more than 2% of our capital.
