Trend-Line Breakout Backtest in Crypto: Fees, Slippage and Break-Even Costs

Trend lines drawn by hand can't be backtested honestly. A mechanical line through defined pivots can.

Short answer

A trend-line breakout rule needs a mechanical line: for example, through the last two confirmed pivot highs (each with N bars on both sides), entering when price closes above it. Pivot confirmation delays the line by N bars; using unconfirmed pivots looks into the future. Define pivots, minimum spacing and the break rule, use next-bar fills, compute break-even cost and compare with a simple channel breakout on the same data.
