Stock Trading Rule No 2: Don’t risk more than three% of your total portfolio on any one stock trade.
Shielding your primary investment is important if you want to be in stock trading for long time. Remember that you are not trying to acquire the company, you are merely trading their stocks to gain profits.

Stock Trading Rule No 3: If you are wrong, cut your losses at maximum of 10% (or less?)
A very important rule. Many people commit the mistake of sticking a loser while intelligent traders will minimize their loses and move on. The significant tip in this case is to keep stop loss points and reduce your losses if your predictions went incorrect. Keep to your stop losses and keep in touch about the performance of your share.

Stock Trading Rule No 4: Always set price targets.
Before share trading plan price targets. Sell off your stocks when your price targets are achieved. A share price can rise too high in a short time and also can drop too drastically.

Stock Trading Rule No 5: Don’t break the rules.
Like I mentioned before you should stick to the rules to achieve profit in share market
