Summary

Backtesting can be done on up to 10 symbols in the professional subscription. Multiple symbols can be submitted by typing them in, pasting a single column list from Excel, or pasting a two column list of symbols and weights. This allows investors to input a current portfolio weighting and see how an options strategy would have performed. Daily returns are multiplied by weightings and added together to produce backtest statistics.

Backtesting can be on one symbol in the basic subscription or up to 10 symbols in the professional subscription.

There are three ways to submit multiple symbols to the backtester:

  • Type┬ámultiple symbols into the Symbols input box.
  • Paste in a single column list of Symbols from Excel.
  • Paste in a two column list of Symbols,Weights from Excel.

This is useful to investors because you can input a current portfolio weighting and see how an options strategy would have performed. For example, let's say an investor had 25% of assets invested in SPY, 25% in MSFT, 45% in INTC and 5% in AAPL, you could run a long call strategy and see how the backtest performed.

If symbol weightings are not included, symbols are equally weighted.

Each trade for each symbol produces a daily percentage return based on the notional or stock price at the time of the opening of the options trade. This allows stocks of different prices to be weighted more equally.

The daily returns are multiplied by the weightings and added together to produce the backtest statistics.

Day trading, short term trading, options trading, and futures trading are extremely risky undertakings.

Never execute a trade unless you can afford to and are prepared to lose your entire investment. In addition, certain trades may result in a loss greater than your entire investment. Always perform your own due diligence and, as appropriate, make informed decisions with the help of a licensed financial professional.

Commissions, fees and other costs associated with investing or trading may vary from broker to broker. All investors and traders are advised to speak with their stock broker or investment adviser about these costs. Be aware that certain trades that may be profitable for some may not be profitable for others, after taking into account these costs. In certain markets, investors and traders may not always be able to buy or sell a position at the price discussed, and consequently not be able to take advantage of certain trades discussed herein.
