Dear support, I hope you're doing well I built a custom ASCIL study that modifies the price of a limit order, following some indicator. At some point, I get the following message appearing in the Trade Service Log: "Unable to modify order because maximum failed modifications has been reached. Limit: 20" Two questions: - Can I change the limit=20 to something higher ? (or disable it?) - I'm currently manually calling sc.ModifyOrder for that purpose and it fails when the indicator does not change ("Price and quantity (xxx, xxx) for order modification are the same as existing order"), which eventually triggers the "Maximum failed modifications" error. Is calling sc.ModifyOrder the recommended way for this use case or would you recommend doing something else ? Thanks for your help |

You need to avoid a failed order modification. This cannot be changed. It is there to avoid excessive messaging to the exchange. Before modifying check the existing price and quantity of the order and if there are no changes do not do anything. Sierra Chart Support - Engineering Level Your definitive source for support.

Thanks, very clear Quick followup question if I may; My understanding is that sc.ModifyORder returns -1 for all errors correct ? is there a way to programmatically catch what error is raised precisely or do I have to go to trade service logs ? |

No there is not a way to know exactly what the error is programmatically other than checking the Trade Service Log.
