I think it would be useful to be told how much money needs to be matched before your order gets matched.

That would enable you to decide either:

A. I'm about to be matched, so I'll sit tight.

or

B. I'd better take money to close my trade, as I'm at the back of the queue, and it doesn't look like I'm going to be matched before the market moves further against my position.

I agree it would be useful, but I think we've had similar discussions before. BA wouldn't be able to supply that info within their software, it could only come from BF, as they know how many people in front of you have bailed out.
Ultimately, you have to simply note how much money has been matched on that selection, how much money was in front of you when you joined the queue, then calculate what volume needs to be matched on that selection before it gets to you. BA can't do everything, sometimes people need to do some calculations of their own Jeff

Betfair don't expose this information via the API so you can't work it out. You can try and use an estimate as where you are but that is very errant. I am sure there have been lots of threads on this before. Basically as money piles up in front or being you or cancelled it gets scrambled you end up with a very mixed picture of exactly where you are.

financial apps do this but they literally just take the money in front of you less what has been matched. Its not exact but what it does do is give you a worse case scenario of where you are in the que. For markets that have many thousands in the que it may well be useful although I tend to do it manually in my head going from what was in front of my less what the change in volume is so I know roughly where I am in the que

Peter -

Fair enough. :)

Does it follow then that, when an order gets matched in practice mode, it might not have got matched at the same point in time had real money been used?

It's a little more complex than this but if you put an order in practice mode and the queue is £5k, but £5k arrives after you put your practice order in then your practice order will start matching when initial £5k has been matched on that runner in the market. So it will feel very similar to trading for real in terms of how it is matched.

Anomalies occur when the price is matched beyond your current order price. If £5 is matched beyond your current price then we have to matched your practice order in full as the price has moved and all money has been taken. But in reality, especially with larger orders, your initial order may not have matched in full. This is why we warn people to test with real money first when moving off practice mode.
