Of course you can take stronger decisions against daytraders,
but you can also have a stronger opposition from people.
And finally you are not sure whether this strong influence on the market would assure to stop daytraders without any other worse side effects.
I don´t think is a good idea to discard ideas without further discussion... give us at least a reason or comment about it or just don´t say anything.
I am not discarding ideas. But when people suggest something along these lines, they forget that managers here are supposed to
manage their team.
This of course includes making decisions about when to list players, and more importantly - at what price. I think it is counterproductive to let people be able to get away with poor business decisions -- looking at the issue conceptually, the problem with daytrading is not that the original seller is losing money. This is entirely in his control, so he must really be kicking himself. The problem occurs when the trader is allowed to make unchecked profits and make an egregious amount of money without any real penalties.
I think that even without doing anything right now, the situation will get better as the game expands and more good players are offered on the transfer market. But a penalty on in-game performance because of excessive trading and/or having too many players on the roster is a necessity, I think.
