I hate to admit it but I always get myself confused between backing and laying and how to interpret the price and money movements.
ie if I click on the left side of the ladder as far as I am concerned I am offering a price to backers thus I am a layer. But then I get further confused because there times I am laying to greenup the bets and times I am laying because I think the selection will lose. Sorry I know I am not making myself very clear.
I have spent many hours creating triggers in excel with complex formulas (my works of art - which I am rather proud of) but yet I am missing some very basic understanding of the numbers I capture and I am so frustrated.
Say for example £60,000 is the total matched on a selection so far. Could this mean that £20,000 has been wagered on the selection winning with the layers having a liability of £40,000 ?
Or if I want to use the last price matched (lpm I assume is the same as lpt) as a guide to the price movement coming in or going out. I have hundreds of excel sheets where the price is all over the place. I have even seen it go from 2 to 300 and back again, many of the price movements just don't reflect what is happening in real time during a race.
Forgive me I really should give you specific examples but I don't have them to hand right now. I am going back a year or so ago when I thought by capturing the data in real time I could then research the data and come up with rules for triggers. Alas I failed
Your comments are always appreciated - so if I am just being thick then don't hesitate to say so.

Thanks again for your time.
