Tack is a trend-following system for EUR crypto pairs. It doesn't predict the market — it changes heading to ride whichever way it's actually blowing. Walk-forward validated, and honest about the drawdowns.
Every number we show is walk-forward out-of-sample, net of Bitvavo's real fees and slippage. No curve-fitted hindsight.
We run the exact strategy in the open. You watch it win and lose in real time — losses shown as plainly as gains.
The edge is drawdown control, not miracle returns. 30–50% drawdowns are possible. We say so up front, not in a footnote.
An ensemble of trend/breakout models reads closed 1-hour candles. Long or flat only — it's either riding a trend or in cash.
Parameters are chosen on past data and traded on the next unseen window, rolled forward. Only out-of-sample results count.
Every result is net of 0.25% fee + 0.05% slippage per side — the same model live and in backtest, so there are no nasty surprises.
