Professional traders always backtest and verify their trading strategies before risking real money because their livelihood and in some cases, client money, is on the line. The average retail trader usually does not backtest their strategies and that is one of the biggest reasons that they are not able to make the transition to professional trading.
Now that you understand the value of backtesting, I’ll get into some examples of professional traders who backtest, tools you can use to backtest and the details of what backtesting does for professional traders.
Why Professional Traders Backtest
Professional traders backtest because they need to know if a trading strategy works or not. They also need to know detailed metrics about the strategy.
It’s like buying a used car.
Would you buy a used car without test driving it first?
Of course not.
In a similar fashion, a trader needs to “test drive” a strategy to find out if it has an edge.
On top of that, backtesting gives a professional trader important information about the trading strategy.
Some of the key metrics that traders look at are:
- Maximum drawdown
- Potential average monthly return
- Correlation to other trading strategies
- Volatility of the trading strategy
- Risk of ruin
Backtesting also helps professional traders determine the optimal position size, risk management strategy, and identify the ideal timeframe for their trades.
