Questions about the Bars function (or variable):
What are the maximum and minimum values of Bars?
It counts up each time a new bar appears on a chart, but how high does it count? What happens when it reaches the maximum - does the value of Bars remain at the maximum value until the program is shut down? At what point does Bars reset to its minumum value - when it reaches the max, or in some other way?

When you place a pending order with OrderSend(), the function returns the ticket number of the pending order.

Question: When the pending order gets filled, does the filled order have a new ticket number?

When you want to place an order without any slippage limitations (or bounds), how do you specify that in the OrderSend function?

Is there anyway to change the default arrow drawn on the chart when the OrderSend() function places an order? For example I would rather see an up/down triangle than the up-right/down-right arrows it draws by default.
