Best Options P&L Tools for Investing

TradingView

DetailsVisit site

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.

Unusual Whales

Unusual Whales is an options-flow and market-activity platform for traders who want real-time U.S. options trades, dark pool/off-exchange activity, alerts, screeners, news, congressional trading data, and developer API access. It is strongest for alert-driven options and order-flow research, with portfolio tracking, API, WebSocket streaming, and historical full-market options data handled through separate paid surfaces.

GammaWins Calculator

DetailsVisit site

GammaWins Calculator is a free web options payoff and Greeks calculator for traders who want to model single-leg and multi-leg option strategies, visualize profit and loss, inspect Greeks, test volatility assumptions, and share strategy states. It is strongest for trade planning and education before using a broker or more advanced analytics platform. The main caveat is data latency: the calculator currently displays options and stock prices with a 15-minute delay, and planned journal, broker-sync, and paper-trading features should not be treated as broadly available.

MarketXLS

MarketXLS is an Excel-first market data, options, portfolio analytics, screening, and template add-in for investors who want live or delayed financial data directly inside spreadsheets. It is useful for Excel-heavy workflows covering stocks, ETFs, options, mutual funds, crypto, forex, fundamentals, FRED economic data, ETF holdings, portfolio templates, and broker order-ticket integrations. It is not a redistributable market-data API: real-time coverage is tiered, some exchanges require add-ons, and licensing is personal-use oriented.

OptionCharts

DetailsVisit site

OptionCharts is a web-based options analytics workspace for visualizing strategy payoff, Greeks, implied-volatility skew, expected moves, gamma and delta exposure, contract history, and market-wide options trends. It is best for traders who want options research and chart exports, not brokerage execution, a public options-data API, or guaranteed real-time access on every plan.

Options Profit Calculator

DetailsVisit site

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. 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.

TC2000

DetailsVisit site

TC2000 is a long-standing charting, scanning, alerting, paper-trading, options-analysis, and brokerage-connected platform for active U.S. stock, ETF, and options traders. It is strongest for users who want streaming charts, EasyScan, formula-based PCF screening, real-time watchlists, customizable alerts, MT Newswires, paper trading, and options P&L workflows in one interface. Plans are paid, and several real-time or higher-capacity feeds are separate add-ons. TC2000 is U.S.-centric and built for active trading workflows, not broad global fundamental research or long-term portfolio accounting.
