Start Order FIX Session

author image

This part of the FIX API Starter application takes the responsibility to start a FIX API Order Session.

devEnv is configured to specify the running environment.

If devEnv is set to true, that stands for an environment in development. If devEnv is set to false, that stands for an environment in production.

public static boolean startOrderFix() {
  if (!devEnv) {
    if (startOrderFixProd(resetSeqOrder)) {

      return true;
    } else {
      logger.error("Failed to start order service.");
      return false;

  }
