$AAVE 1. Interaction with the Lower Bollinger Band
The chart uses Bollinger Bands (20, 2) as seen in the top left indicator panel (BB 20 2).
Oversold Territory: The price has been in a sustained downtrend, riding down the lower Bollinger Band. Just before your entry, the candlesticks hit and began consolidating right at or slightly below the lower band (86.483).
Mean Reversion: In trading, prices touching or breaking outside the lower Bollinger Band are often considered statistically oversold, suggesting a high probability of a bounce back toward the basis/middle moving average (the orange line at 88.696).

2. Horizontal Support & Price Consolidation
The "Floor" Effect: After a sharp drop from the $100+ area, the aggressive selling pressure stopped. The recent candles started forming a horizontal base (flat consolidation) around the $87.00 - $87.80 zone.
Seller Exhaustion: The smaller bodies of the recent candlesticks indicate that the bearish momentum was losing steam, providing a safer, low-risk entry point with a tight potential stop-loss just below the recent swing low.

3. RSI (Relative Strength Index) Context
Looking at the RSI (14) at the bottom of the chart, it is currently sitting at 39.43.
While not deeply under 30 (the traditional oversold threshold), the RSI shows that the asset has been thoroughly reset from its previous highs. More importantly, the RSI line is beginning to flatten out and curve slightly upward, mimicking the price stabilization and hinting at a local momentum shift.
Summary of the Setup
The Strategy: This looks like a classic mean-reversion / support-bounce play. You bought the asset at a major local discount, betting that the selling pressure is exhausted and the price will rally back up to test the middle Bollinger Band (orange line)
