Many people chase pumps and dump on dips by watching candlestick charts; I pay more attention to differences in timing across exchanges. The system ranked them by “5-minute cross-exchange dispersion”: the same asset rising on gate while falling on mexc at the same time (for example, at one point IRYS was up 31.8% on mexc while down 0.8% on binance). This mix of red and green is where front-running and arbitrage opportunities arise.
