Wickra Impact — C#

.NET bindings for the Wickra Impact market-impact backtester over its C ABI hub. An Impact is built from a spec JSON and driven over a JSON boundary, so the result is byte-identical to every other Wickra Impact binding.

Install

dotnet add package Wickra.Impact

The package ships the native C ABI library per runtime identifier under runtimes/<rid>/native/. For a local build, cargo build -p wickra-impact-c --release places the library in target/release/; the bundled DllImportResolver probes the Cargo target/ tree, so tests and apps in the repo find it without extra steps.

Usage

using Wickra.Impact;

const string spec = """
{"strategy":{"spec_version":1,"symbol":"IMPACT","timeframe":"1h",
 "indicators":{},"entry":{"ge":[{"price":"close"},0]},"exit":{"in_position":true},
 "sizing":{"type":"fixed_qty","qty":10.0},
 "execution":{"order_type":"market","fill_timing":"next_open"}},
 "book_model":{"kind":"orderbook_walk"},"participation_cap":1.0,"latency_ms":0}
""";

using var impact = new Impact(spec);
string report = impact.Command($"{{\"cmd\":\"run\",\"data\":{data}}}");
Console.WriteLine(report); // the report carries the market impact a naive backtest hides

Surface

  • new Impact(specJson) — build a backtest handle ("{}" defers to a later set_spec). Throws ArgumentException on an invalid spec.
  • Command(cmdJson) — apply a command envelope ({"cmd":"...", ...}) and return the response JSON. Commands: set_spec, run, version.
  • Impact.Version() — the library version.
  • Dispose() — free the native handle (using recommended).

Determinism

The fill engine lives only in the Rust core; this binding forwards the command string verbatim, so a given request produces the byte-identical report here and in every other binding — the exact cross-language golden invariant.
