Dear all,

Recently, I updated Python and oTree (--> 6) recently. Since then, it seems that it is impossible to set PLAYERS_PER_GROUP to 1. I could do that using my earlier environment.

I saw some posts where it is recommended to set it to None but, for my needs, it is not the same.
My app is a continunous double auction and groups are used as markets and, in a given market, the participants are competing and face the same order books.
But if I want them to be each in a their own market, I set PLAYERS_PER_GROUP to 1.
If I want all of them in the same market, I set PLAYERS_PER_GROUP to None.

Is there a workaround for this?
Alternatively, could 1 be a possible value for PLAYERS_PER_GROUP?

Thanks a lot.
Rudy
