Tradezella Alternative with a Free Tier: Journal + Paper Sim

Tradezella is a polished, journal-first product known for its Zella Score and bar-replay backtesting. Tapeboard ships a journal with its own published 0-100 Tape Score, plus a full research + scanner stack and a free simulator that bridges closed trades straight into the journal — so practice and review live in one tab, with a real free tier.

• You want to practice in a simulator and have those trades flow straight into your journal — Tapeboard bridges sim closes into the journal automatically; Tradezella has no live paper-sim.
• You want a real free tier to try before paying — Tradezella is paid-only with no free trial.
• You want journal + scanner + charts + SEC filings + economic data in one tab, not a journal you bolt onto separate tools.
• You want a transparent, reproducible score — the Tape Score's exact weights and formulas are public; the Zella Score's are not.

• You want the deepest backtesting in the category — Tradezella's Backtesting 2.0 with second-level data is best-in-class; Tapeboard's Market Replay is bar-based.
• You want autonomous AI that auto-tags every trade and writes your session review without prompting — Zella AI is further along than Tapeboard's on-demand journal coach.
• You're buying into the Zella Score brand and the TradeZella University / Discord community specifically.
• You journal real broker trades exclusively and have no use for a research/scanner stack.

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.
