Moore Tech Insight

PowerLanguage code repair is often about behavior, not just syntax. A MultiCharts indicator or strategy can compile but still behave differently than expected because of data series, strategy properties, calculation timing, or platform differences from TradeStation.

Moore Tech handles MultiCharts programming for PowerLanguage indicators, strategies, repairs, conversions, and workflow tools.

What counts as PowerLanguage repair

Repair usually means the code exists, but it does not compile, does not display correctly, or does not match the intended MultiCharts behavior.

Common repair requests include:

  • compile errors in PowerLanguage
  • indicator plots or alerts that do not match the rules
  • strategy entries or exits that differ from expectations
  • multi-data behavior that is hard to verify
  • TradeStation EasyLanguage logic that needs MultiCharts cleanup
  • older code that needs modernization before extension

For these projects, send the code and the platform context. A screenshot of the problem is useful, but the source file is usually required.

What to send

Send:

  • PowerLanguage source files
  • MultiCharts version
  • chart symbol, timeframe, and data series
  • screenshots of inputs and strategy properties
  • examples of correct and incorrect behavior
  • TradeStation source files if this started as a conversion
  • broker or data-feed details if they affect the result

If the issue is strategy-specific, include the strategy properties and assumptions used during testing.

Conversion problems are common

PowerLanguage is similar to EasyLanguage, but TradeStation-to-MultiCharts conversion still needs review. Data handling, strategy settings, order assumptions, and platform behavior can create differences even when the syntax looks familiar.

If you are converting from TradeStation, review the TradeStation to MultiCharts conversion guide before requesting repair work.

Repair or rebuild

A rebuild may be cleaner when the current code is incomplete, the original assumptions are undocumented, or the conversion introduced too many unknowns.

The old code can still define the desired behavior, but the quote should be scoped around the actual work needed to make the MultiCharts version reliable.

Practical next step

Start with MultiCharts programmer services when you have broken PowerLanguage, a confusing strategy result, or a TradeStation conversion that does not behave correctly.
