Written in advance: This is my first sharing, and also a learning process. If there are any inaccuracies, please correct me, esteemed experts.
MA
This refers to moving averages, which can be roughly considered as the average of traded prices. Common types include MA5 (the five-day moving average), MA10, MA50, MA200, etc. Moving averages can be used to identify trend directions. Medium to long-term moving averages can serve as price support or resistance levels. If a short-term moving average crosses below a long-term moving average, such as MA5 crossing below MA200, it may indicate a buying opportunity.
VOL
This refers to trading volume, which often serves as a corroborative role. For example, when the price suddenly rises, if there is no corresponding large trading volume as a reference, it can be considered a short-term pump by the operator. If one blindly chases higher prices at this time, they may find themselves standing guard at the peak. The same applies when the price is falling.
RSI
Relative Strength Index. Taking RSI14 as an example, it is the average increase over the past 14 days divided by the average decrease. RSI ranges between 0 and 100. When RSI is greater than 70, it indicates that the asset is in an overbought range, and a price pullback may occur. When RSI is less than 30, it indicates that it is in an oversold range, and one can consider gradually building a position, as a price reversal may happen. Of course, as a lagging indicator, specific situations still need to be analyzed individually.
BOLL
This refers to Bollinger Bands, which typically consist of three lines: UB, MB, and LB. MB, or the middle band, is often a moving average over a certain period. UB is the middle band plus two standard deviations, while LB is the middle band minus two standard deviations.
When the long-term MB approaches the UB line, it represents an upward trend. When the short-term MB approaches the UB, it may indicate a certain level of overbought conditions.
No technical indicator can replace human judgment.
