Usually, we are trading with market, and we have our own trading logic. But , after you are trading for a long time , you will find you are trading with yourself and the biggest enemy is you.
You may have a good trading logic , and you always earning money from the market , but you are still afraid of lossing, am i right?
Every trader should believe in his own trading logic just like a belief, you can't move it. Lossing are not terrible and you should like it.
So i have some advices:
1. make sure you are believe in your trading logic
2. record the reason when you open trade
3. take profit and stop loss strictly
4. back to the records when you close trade, and think why you are earning or lossing
5. according to the records , if you find something wrong with your trading logic, fix it
6. add your trade into a trade journal (advice from @GreatArkansas)
7. do the things 1-6 above again
Does any trader record the reason of opening trade? And how do you guys practice it? Let's talk about it.
Number 3 is really important. Setting a trail stop means to control your greed as well and having a stop-limit means valuing the money you invested.
Like others said to treat your trade as your business, not a gamble.
