Short selling in bull run can be dangerous, but still when I see a resistance zone I can't stop myself from short selling! what yours opinion in this case? Should I continue short selling in this bull run, or should prevent myself from doing this?
Short selling is a very risky maneuver especially in this market and under the current circumstances, since you do not really know when the price could go up all of a sudden and your position could become heavily compromised, especially if you were to use leverage as well, so if you are going to do it anyway I will recommend that you use a stop loss and that you abide to it, otherwise your losses could grow very quickly if there is a positive news and the market reacts to it.
Instead of keeping yourself with risky strategies, you should plan your investment with a strong financial investment so that the level of risk can be reduced relatively. Your stop loss concept can be very helpful if traders plan accordingly. But I would say try to keep yourself busy with buying in downtrends and getting a holding trend.
