What InvestTester does differently:
- Free with no account: There is no login and no limit on history. Open the page, type the tickers and press Simulate.
- Any market: Tickers come from exchanges around the world, so a portfolio can mix AAPL, VWCE.DE, 7203.T, PETR4.SA and BTC-USD. See Market Tickers.
- Your currency: A suffix converts an asset with the daily exchange rate, so you can see the S&P 500 in euros, yen or reais (e.g. SPY:EUR). See Ticker Modifiers.
- Brazilian fixed income: SELIC (the base of the CDI), IPCA inflation, the IMA-B index and Tesouro Direto bonds are built in, next to B3 stocks, FIIs and ETFs. See Brazilian Tickers.
- Strategies in JavaScript: The Algo Trading page runs your code day by day over the same data, in the browser, with orders, short selling and margin. There is nothing to install.
- Results as links: A comparison is an address such as /compare/SPY/QQQ, which runs the simulation when it opens, so it is easy to share.
- Six languages: English, Portuguese, Spanish, French, Japanese and Chinese.
- Open method: The Methodology page gives the data sources and the formula of each metric.
InvestTester vs Portfolio Visualizer:
Portfolio Visualizer is the reference tool for US investors. It has asset class data from 1972, Monte Carlo simulation, an efficient frontier, factor regression and tactical allocation models. Its free plan runs without a login, with up to 15 assets, limited history and no results for the current month. The paid plans start at $30 per month, billed annually. Its data covers US and Canadian securities, mutual funds and ETFs.
Choose Portfolio Visualizer for factor analysis, optimization and Monte Carlo. Choose InvestTester if you need tickers from other countries, another currency, full history at no cost, or your own strategy in code.
InvestTester vs testfol.io:
testfol.io is strong on long history and leverage. It has simulated tickers such as a total return S&P 500 series that goes back to 1885, models the cost of leveraged funds, and adds tactical allocation and Monte Carlo tools. The backtester runs without an account, some tools need one, and the paid plans start at $12.50 per month, billed annually. Its help page states that only US stocks, funds and ETFs are available.
Choose testfol.io to test US leveraged ETF strategies over many decades. Choose InvestTester for assets outside the US, crypto, Brazilian fixed income, or strategies in code. InvestTester has history only as far as its data provider has it for each ticker.
InvestTester vs Curvo Backtest:
Curvo Backtest is free and made for the European index investor. It extends the history of young ETFs with the data of their index, and it covers more than 740 funds. All its data is in euro, and only funds available in Europe can be analysed.
Choose Curvo for a long history of UCITS index funds. Choose InvestTester to add single stocks, US ETFs or crypto to the same portfolio, or to work in a currency other than the euro (e.g. VWCE.DE with AAPL:EUR and BTC-EUR).
InvestTester vs Lazy Portfolio ETF:
Lazy Portfolio ETF compares up to four lazy portfolios from a fixed list of ETFs and asset classes, with rebalancing bands, a trend filter and a Monte Carlo tool. InvestTester accepts any ticker, including single stocks, and compares up to 3 portfolios with deposits and a rebalancing frequency. See Portfolio Backtest.
InvestTester vs Composer and QuantConnect:
Composer builds strategies with a no-code editor and AI, and trades them automatically in a brokerage account. It is for users in the US, with US stocks, ETFs and options. QuantConnect is a professional platform for strategies in Python or C#, with intraday data, many asset classes and live trading through brokers. It needs an account, and its paid plans start at $84 per month.
InvestTester does not send orders to a broker. Its Algo Trading page is a quick way to test an idea with daily prices in JavaScript, with no account and nothing to install. Choose Composer or QuantConnect to trade a strategy with real money or to use intraday data.
InvestTester vs Brazilian comparators (Mais Retorno, Investidor10):
Mais Retorno has a comparator of funds, stocks, FIIs and fixed income against the CDI and the Ibovespa. Its free plan compares up to 10 assets and saves 1 simulation, and the Prime plan removes these limits. Investidor10 compares up to 5 assets over fixed windows of 2, 5 and 10 years, with the CDI and the IPCA as references.
Choose them for Brazilian mutual funds and for the fundamentals of each company. InvestTester simulates a complete portfolio with weights, monthly deposits and rebalancing over any date range, and puts Brazilian and foreign assets in reais in the same portfolio (e.g. IVVB11.SA, BTC-USD:BRL and SELIC.SA).
What InvestTester does not do:
- Monte Carlo simulation, portfolio optimization and factor regression.
- Simulated history from before a fund existed, and mutual funds that its data provider does not list.
- Fees, taxes and intraday prices. See Methodology for the simulation rules.
- Live trading or a connection to a broker.
