Expectancy and Strike rate?

[mulberryhawk]

Hi,

Im new to pre-race trading and was hoping someone would be able to clear something up for me.... I am a little confused on the strike rate and expectancy and how to actually calculate them.

Should these be calculated on your overall profit or loss on an individual race or should they be calculated on the total number of trades you perform on an event?

I know that Peter thinks its essential that a trader keeps records. But if you are both swing trading and scalping is is better to keep two different sets of records so your strike rate and expectancy are more accurate for each?

All help and advice would be greatly appreciated...

It's better at the start to have something than nothing, so I suggest keeping a record of strike rate by race. From there you can start digger a bit deeper.

If you use the Betfair betting P&L and also archive your betting history you will have tons of data to go back on and work with. Some good spreadsheets in the spreadsheet area for you to use.

Thanks for the reply bet angel,

So what your saying is initially i should just work out my strike rate by calculating how many races i am proftable on in a trading session? Then i presume i should start to look at my average profit per race and my average loss per race to calculate my expectancy...?

I know people tend to often characterise themselves as a scalper or swing trader. But if you aim to be good at both techniques,do you seperate the data?

In order to find out which trading style you are better at and which one you need to improve on, would you need to keep seperate strike rate and expectancy data for more accurate findings?

thanks in advance:)
