I generally prefer Swing Trading Style and I use the strategy of Demand & Supply, I find it very effective. I have more interest in trading stocks although sometimes I go for options in Index. My strategy is quite simple, I follow the 1:3 Risk-Reward ratio.
It takes weeks for me to choose a particular stock, I do not take entry until and unless the price of a stock enters in the demand zone. Once the stock comes into demand zone wait for the reversal, I analyze it with the help of various indicators like Fibonacci, SMA, EMA etc.
I strictly follow stop loss cause many of the times I have seen the bad effects of not following discipline. Beginners who are opting for day trading must understand that if you will not follow the basic rules you will pay the cost for it. You can read about the trader characteristics in this day trading guide, it will help you to know what kind of attitude you must possess when you are trading.
Now, let's come to the exit as I already said that my trade continues till 2-3 days if somewhere between it triggers my stop-loss I choose to take exit cause it make me realize that the trend is not in my favor, it's better to get out. And If the trend is in my favor, everything goes as I expected then I choose trailing stop-loss as it secures my profit and also I can go along with the trend for long.
