Why is 'NONE' not allowed as a 'selfTradePreventionMode' value for BTC/FDUSD ?

Why can’t I set set selfTradePreventionMode to ‘NONE’ for the BTC/FDUSD trading pair?

Some changes I’ve made to my API trading are now causing orders to be cancelled due to selfTradePreventionMode. This is causing problems for me.

When I try to set selfTradePreventionMode for Spot Orders via the API using the BTC/FDUSD trading pair to NONE I get an error:

“APIError(code=-1013): This symbol does not allow the specified self-trade prevention mode.” and I can see in get_symbol_info that the allowedSelfTradePreventionModes are:

 ['EXPIRE_TAKER',
  'EXPIRE_MAKER',
  'EXPIRE_BOTH']

Hi, I think it’s server side setting that NONE is not an option for this symbol.

Thanks

Yes it is ‘server side’ - and like I said in my post - calling get_symbol_info shows that ‘NONE’ is not available as an option.

My question was why is ‘NONE’ not available as an option for BTC/FDUSD?
Can BTC/FDUSD be updated so NONE is an option?
