   TradingView

   TradingView is a chart-first market analysis platform for traders who want powerful charts, screeners, alerts, Pine Script, paper trading, and broker-connected trading across many asset classes. It is strongest when technical analysis, custom indicators, strategy testing, watchlists, and real-time market monitoring are part of the same workflow. The free Basic plan is useful for trying the product, but active users usually run into limits on charts, indicators, alerts, watchlists, and historical bars. Some real-time exchange data is sold separately.

   Testfol.io

   Testfol.io is a free web-based portfolio backtesting and analysis toolkit for investors who want to test allocations, cashflows, rebalancing rules, tactical signals, leverage, correlations, and historical risk/return before moving to a spreadsheet or paid analytics suite. It is strongest for portfolio-level experimentation rather than intraday monitoring or live account management. Anonymous use is available, while a free account unlocks higher limits, cloud saves, and sign-in-gated tools. Backtests depend on historical assumptions and end-of-day data, so they are not trade execution or forward-looking guarantees.

It combines ETF screening, fund profiles, stock-to-ETF exposure lookup, watchlists, transaction-based portfolios, savings-plan workflows, simulations, rebalancing, attribution, and mobile alerts. It is strongest for European ETF investors, not U.S.-listed ETF workflows, broker execution, tax-lot accounting, or public API access.

   MesoSim

   MesoSim is an options strategy backtesting platform for traders who need low-code strategy definitions, multi-leg simulations, risk graphs, Greeks, volatility surfaces, margin models, and paper/live workflow paths.

   Portfolio Visualizer

   Portfolio Visualizer is a web-based portfolio analysis suite for backtesting portfolios, testing asset allocations, running Monte Carlo simulations, optimizing allocations, analyzing factors, checking correlations, and researching funds. It is strongest for DIY investors, analysts, and advisors who want evidence for allocation, withdrawal, and risk decisions without building every model in spreadsheets. The free tier is useful but constrained, while Basic and Pro add larger portfolios, YTD results, saving, imports, exports, and commercial-use support on Pro. It is not a broker, live portfolio accounting system, or automatic rebalancing platform.

    Options Profit Calculator

    Options Profit Calculator is a free web toolkit for modeling option payoff diagrams, profit/loss tables, multi-leg strategies, probability estimates, and what-if scenarios before placing trades elsewhere. It has very high search demand around options profit calculator and commercial demand around strategy calculators and backtesting, but its public profile still shows delayed 15-30 minute quotes and real-time data as coming soon. Premium beta adds advanced calculators, custom strategies, comparison tools, an options backtester, and ad-free use. It is not a broker, real-time trading terminal, options advisory service, or substitute for risk management.

Monthly and annual plans differ by account limits, storage, playbooks, mentor invites, and advanced workflow access. TradeZella is not a brokerage; trades are executed elsewhere and imported for tracking, analysis, backtesting, and review.

It is not an automated strategy engine, and seconds-level data plus broader asset coverage are Pro-gated.
