Diagnose why one authorized-source custom cTrader indicator stopped building, loading or plotting after a cTrader Desktop or Algo API update.

You receive: • one current failure compared with the last known working environment • complete build diagnostics and dependency boundary review • clean-instance loading, calculation and plotting evidence map • a smallest reproducible source-safe fixture where feasible • ranked findings and a separately priced repair scope

You provide editable C# or Python source you own or are authorized to share, current and last working cTrader versions, operating system, build output, symbol, timeframe, parameters, dependencies and reproduction steps.

This two-day scope covers one indicator and one reproducible update-related failure. Source repair, redesign and new features are separate. I do not decompile protected or compiled-only products, request credentials, operate a live account or promise trading performance.
