The blue lines in the chart represent major swing high and low in the 75-minute time frame. Unless the price moves above a prior swing high, it would make sense to look for shorting opportunity at resistance. This is the basic logic behind trading.
People tend to get into trouble when they focus on a lower time frame, without having the context of the higher time frame. In a downtrend, there would be opportunities to go long and make money in a lower time frame. But, do not get greedy and hang around on such trades as they are counter-trend in nature.
Notice the red flag in the chart which represents swing low that has been breached this week. This is a sign that the downtrend is still in force.
Unless the price clears the swing high at 8807, there would be a strong case for a slide to a new low below the recent low of 8,506.
