// Is the Tape Score the same as the Zella Score?
Both are 0-100 performance grades, but the Tape Score's methodology is fully published — the five components (profit factor, R-expectancy, win rate, consistency, drawdown control), their weights, and the normalization formulas are at /methodology/tape-score. It's account-size agnostic and computed over the same engine the simulator uses, so a paper trade and a real trade are graded identically.
// Does Tapeboard have a free tier? Tradezella doesn't.
Yes. Tapeboard's simulator is free, and the free journal shows your dashboard and calendar on a rolling sample so you can feel your expectancy, R, and drawdown before paying. Tradezella is paid-only with no free trial.
// Can I backtest like I can in Tradezella?
Tapeboard has Market Replay — pick a past session and play it forward bar by bar. Tradezella's Backtesting 2.0 uses second-level data and is deeper; if tick-level backtesting is your core workflow, that's where they win.
