Quick data snapshot: $SOL |Daily RSI(14) 24.9|Oversold
What it is: When Wilder first introduced RSI, he used futures market data. These days, pretty much every charting tool comes with it built in.
Common interpretation: RSI levels vary quite a bit between different coins. Smaller coins with higher volatility are also more likely to hit very high or very low values, so be careful about applying the same thresholds across the board.
Calculating position size based on where you place your stop-loss is much more reliable than picking a size by gut feel.

Just chatting—this isn't advice.
