Is there a daily message for this, that you can detect with the api? (between 9pm and 10pm)

If not what is the workaround to show the daily profit and loss of an order since the lastest rollover?
for the moment I have set 9:00pm, and map the order with the instrument price at this time

thanks

edit: may I suggest to provide the last rollover time in IClientInfo and IAccount interfaces (just rollover close)

On rollover the position open price (i.e., IOrder.getOpenPrice) gets adjusted to resemble the rollover amount that has been applied to the position. On such open price change an IMessage.Type.ORDER_CHANGED_OK message arrives in IStrategy.onMessage. Thus to get the rollover amounts you have to store the previous open price, get the difference with the current open price and then multiply it with the position amount. Position's daily profit and loss you can simply fetch shortly after the settlement by calling IOrder.getProfitLossInAccountCurrency.

Thanks

Just to be sure getProfitLossInAccountCurrency returns the daily pnl in account currency? or the pnl since order fill time?

edit: after checking, it's probably pnl since creation time

How precisely is the rollover notified with ORDER_CHANGED, since there is normally 1 close, followed by an open order I guess?
there are 2 events or just one?

The fill time.
Just one message per position, you can make sure of this by leaving overnight a strategy which prints order-related messages.
