> Do those who do not have such problems have to replace the robots with the new updated version?
No, you don’t need to do it.
Some brokers do not require settings of the “type_filling” parameter when sending orders.
The original robots were designed without that option because FTMO and MT5 from MetaQuotres do not need it.
However, we see that traders use these robots on brokers with custom settings, which require Order Filling Type to be set.
