This run ported the hyperopted Freqtrade 'Supertrend' strategy line for line to LINK spot on 1h bars, using six incremental Supertrend state machines plus the original ROI, stop and trailing exits. It took 894 trades from 2019 to 2026 and lost about 0.24% per trade after fees, roughly -0.04% before them, so fees were not the root cause. At backtest review, after 2 iterations, the analyst abandoned it for negative expectancy, an inverted payoff (capped wins against losses running to the deep stop) and no forecasting information in the signal; it never reached optimization. The rejection applies only to this LINK spot port, not to the original on its hyperopted pairs. A separate, unverified concern about impact-cost accounting behind the -100%/liquidation headline was passed to the operator for a ledger review.
