Every time the RSI line comes back through and breaks a downward trend, TQQQ 1.77% goes up. Can track back to 2016 and observe. Quick useful edge. Shorter timeframes and longer have shown consistency. When there is consolidation some brief whip saw will be found but otherwise solid strategy. Try it yourself.
If adding macd and stoch and wait for macd to cross back over (up) and stoch to cross over (up) it takes a few days to confirm but wades out any whip saw and still catches some healthy profit. Key is identifying when to get out, support lines, resistance lines, have either stops or monitor. If anyone has better ideas on exit points to protect profits please comment.
