📊 Relative Strength Index (RSI)

                        RSI = 100 - (100 ÷ (1 + RS))                    

                            RS = Avg Gain ÷ Avg Loss (over 14 periods)                        

                            Avg Gain = SMA of gains, then smoothed: ((prev × 13) + current) ÷ 14                        

                            Avg Loss = SMA of losses, then smoothed: ((prev × 13) + current) ÷ 14

Electronic trading in the early 1990s changed everything. When stocks moved from fractional pricing to decimals in 2001, spreads tightened further, enabling precision scalping.
