In some cases, the results displayed by Builder in the Strategy View dont match the results I get when I run the strategy in TradeStation. Am I doing something wrong?
There are several possible explanations. One possibility is that the date ranges of the price series are different between Builder and TradeStation. It’s also important to set the “Maximum number of bars study will reference” in TradeStation (Format Strategies, Properties for All) to the MaxBarsBack value listed in the Performance table. This will insure that the calculations start on the correct bar. Also note that Builder deducts the trading costs once per trade, whereas TradeStation deducts costs once “per side”. For example, if your trading costs are set to $25 in Builder, they should be set to $12.50 in TradeStation. Even with all the settings correct, there may be small differences. Oftentimes, these result from rounding errors and other small differences that are unavoidable. For example, if an oscillator is compared to a fixed value, such as 80.0, using the less-than-of-equal (<=) operator, there may be a bar where the value calculates as exactly 80.0 in Builder but as 80.00000
