A low RSI doesn't necessarily mean a decline; it depends on 'why it is low'.
RSI, or the 'Relative Strength Index', reflects the relative strength of 'recent gains vs losses' rather than an absolute direction.
Therefore, sometimes you will see a very low RSI, but the price remains flat and does not decline. This is because it has already dropped too much beforehand, and even if it only consolidates afterwards, the RSI will remain low—this does not mean that it will continue to decline.
At this point, it is important to consider the structure. For example:
If the price is consolidating near a structural support level and the RSI is flat at a low level without making new lows, it indicates that selling pressure is waning, and it may be forming a bottom;
Conversely, if the RSI is low but the structure continues to make new lows, it may indicate that the downtrend is not over.
In summary:
A low RSI indicates that bulls are weak, but it does not mean that bears can still push down. It is essential to see whether the structure continues to break down; RSI is merely a momentum reference, not the direction itself.
Thus, 'structure' is the most important aspect in trading; it is the core.
Indicators like RSI and KDJ are used to determine if it is a bottom, accumulation during consolidation, or if the structure is continuing to decline (not finished falling) and other situations.
