Comprehensive Portfolio Modeling
Define and observe your portfolio’s characteristics.
A birds-eye view of the backtest configuration including position entry and exit mechanics, strategy start and end dates, and more.
Starting Capital and Leverage
Define a maximum leverage target and see how much starting capital would have been needed to execute a strategy, or specify a fixed amount of starting capital and see whether a strategy would have generated a margin call.
Win Rate Statistics
Observe the count of trades, how many were held till expiration vs managed, the count of losers and winners, the average loss and win, and the overall win rate.
Margin and Commissions
Decide whether margin collateral should be held in 3-month US treasuries earning the risk-free rate or something more exotic.
Define the commission rate to use throughout the backtest.
Discern how collateral allocation and trade fees influence the bottom line.
Using the portfolio’s start and end values and the backtest start and end dates, the annualized geometric return (CAGR), annualized volatility and risk-adjusted return (sharpe ratio) are calculated.
Identify the portfolio’s most extreme activities such as max drawdown, max drawdown duration, max drawdown date, best and worst trades and best and worst monthly return.
Receive granular reports, trade logs and any additional resources used.
Review high-level equity curve charts and tabular, side-by-side performance characteristics for all backtests in the commissioned research.
Review a simulated 10-backtest summary spreadsheet on fictitious underlying “XYZ.”
Dive deep into strategy characteristics like accumulated trade commissions, running margin utilization, interest earned on portfolio cash, portfolio drawdowns and more, each calendar day in the backtest.
Trade Logs and Supplemental Data

Worth Every Penny
⭐️ ⭐️ ⭐️ ⭐️ ⭐️
I appreciate the hard work Mitch at spintwig.com did backtesting a complex trading strategy for me. His research was worth every penny!
His backtesting not only confirmed some trading pattern suspicions that I had, but he also uncovered a lucrative pattern I had not even considered. I highly recommend his backtesting service without reservation!
