Rules of the top strategy

Breaking above the channel top (average plus a multiple of volatility) signals an upside breakout.

Method and caveats

Past performance does not guarantee future returns. Parameters were selected on the same full-history sample using sharpe over 40 trials per strategy, so results contain in-sample bias. 0.5% trading costs are included; taxes, slippage and rejected orders are not.
