Dear all,
As I said in a previous forum I'm just in the beginning of understanding oTree.

I really don’t know even where to start for this: Iattach a screen of the task. I would need that the subject wallet will update for every round. If you see the screen there is a sentence "You currently have.." and down there is the choice task with a price for a stock and they can decide if buy, sell or hold. 
What I would like to have is that, for example, if they BUY for the proposal price, the round after the stock in the wallet will be 6 instead of 5 and the amount of cash will be that number - the price they bought the stock. And the opposite for the SELL decision.

Thank you in advance
Lorenzo.
