1. Trade at your own risk - You should know that investing, gambling and trading is somehow the same because you are not sure that you could win the prize, so expect that you could win and you could lose your money.
2. Limit your budget - always limit your budget for trading, you should use only those extra money you have, instead of spending it on some other things, you may use it for trading, at least you made something to make it profitable.
3. Do not be greedy - There are many people who suffered from being greedy, they tend to spend all their money because of thinking that they could still make more money but instead of earning they have lost their money. ALWAYS KNOW WHEN TO STOP AND CONTINUE TO TRADE.
4. Learn from your own mistake - Instead of being sad because of losing try to think on some other thing why you get lost and think some good strategies to overcome those mistakes.
If practically all traders can follow the above-mentioned advice, I believe it would be beneficial since traders will know exactly what they are doing and what they can anticipate in terms of profit. Traders will also be aware of when to sell and when to purchase. Most traders are held back by greed; they can't afford to take a small profit and walk away, so instead of waiting for more, they end up losing practically all of their profits.
These suggestions are quite useful, and I am confident that they will effectively lead and assist novice traders.
