QATS Strategy Builder: what you can test without code
How to use a strategy builder to specify trading rules and compare backtests.
In brief: Write down precise entry and exit rules. Compare two versions on the same period, then run your chosen version on a different period. Account for fees and slippage so the backtest does not overstate what you could achieve in the market.

QATS says you can build rules without writing code and test them against historical data. That can help you compare versions of a strategy before entering an evaluation. Results depend on the data and assumptions and do not predict live results.
