A description of the changes proposed in the pull request:
Problems discovered by chance: When using okx_perpetual as the connector for strategic trading, There is a probability that the entire strategy robot cannot operate normally due to the failure of the funding info request (print Connector Not Ready per on tick). This might be related to the startup time. Since the strategy failed stably around the time period of 15:09:18UTC+0, 8th May, 2025, but a similar error has never occurred before. This situation where the entire strategy fails to start due to a single error can be completely avoided by adding retries.

Tests performed by the developer:
After adding retries, the strategy was repeatedly started in the same environment and with the same parameters, and no similar errors continued to occur or other errors were introduced
