Many will argue about which one should be the priority:
1. Understanding the chart for best Entry and Exit
2. Money management.
because these two things determine whether you make a profit or a loss. Money management is very important, especially during a bear market like today. without it one will never know that what they chose was wrong. understand the chart, this is also important. You never know when it's time to enter the market, take profit, cut loss, or the direction of the trend. without knowing this, one will be very worried when they buy/invest even though the market is bull.
I personally always prioritize these two things in my every investment plan. so even though I had a loss, it was within the normal range.
