Back price dif over question
« on: 24 May 2012, 18:28 »
hi all

what would you say the price would have moved from/to:
i just want to get an idea of what greater than -.60 actually means


say 3.00 to 2.40

or 2.40 to 3.00

thanks



Checking condition: and  Selection's Back Price Dif over 0.05 min. is equal or greater than -0.60
Condition is true. valid for 1 selections: Swan Song.

Hi
I think that condition is true for both your examples. It should return false if the price falls below 2.40 from 3.00, otherwise true

hi
your 3 to 2.40 would be correct.
because from 3.00 odds the tick difference is .02.
so from 3.00 to 2.40 is -30 alterations times .02(ticks)= -.60
so, if you want to go greater than -.60, you would be betting on anything above 2.40.
BUT, if you wanted to go below 2.40.
it would be less than -.60.

thanks fellas


i was expecting/wanting the condition i added to mean:

"If the last traded price has fallen by more than 0.60 over 0.05 mins then return true"

i.e - if the price has fallen from 3.00 to 2.40 or 5.20 to 4.60 or 2.10 to 1.50 etc in the past 0.05 mins then return true.

what would i need to change to reflect that ?

thanks again..

Hi
Selection's Back Price Dif over 0.05 min. is less than -0.60
this is for back price and not LTP

Cheers.


A condition of: Last traded price dif over 0.05 mins is less than -0.60 is what would be perfect it seems.


I feel that the movement of the last traded price would be an accurate reflection of whats going on in the market rather than the movement of the available prices

Would you know what the manual work around would be to reflect the movement of the last traded price ?

thanks

Hi
I think it could be done using user variables, but it might be a bit cumbersome given the short timeframe for the calculation.
The logic would be:
record last_traded to uservar1
3 seconds later record last_traded to uservar2
subtract one from the other and you will have your last_traded Dif over 0.05 mins

It might also be able to be calculated in an expression, but I’ve not had the time to try it.
