Increased stakes formula

Hi mcbee,
Thanks for the formula.
Here's what I'd like to do. A little more advanced than I earlier described.
I have 2 trigger blocks, one for Fav and one for Second Fav.
Bets as follows:The amount formula is only for the 2Fav
2Fav trigger 1st bet  4.00  2nd bet 10.00 subsequent bets 10% higher than previous bet
Fav  trigger  all bets 10.00
The triggers fire alternatively.
example
Nadal   2.30    4.00
Murray 1.70    10.00
Nadal   2.16    10.00
Murray  1.62    10.00
Murray   2.40    11.00
Nadal   1.50    10.00
Nadal     2.10    12.10
Murray   1.20    10.00
Nadal     3.60    13.31
The formula would need to ignore player as it is fav or 2fav related.
I started work on the below formula but needs quite a bit of modification.
 IF(hist_1_backa>0,10+hist_1_backa*1.10,4)
Thanks again mcbee

Hi,
If 'hist' is used for setted markets, what is used for unsettled ones (in-play) ?
bm_backa relates to last back amount matched.
What is code for 2nd last back amount matched ?
I cannot find this in the manual.
Thanks as always

Hi
for a selection:
bm_1_backa
bm_2_backa
bm_3_backa
where 1 is the last, 2 is the second last, 3 is the third last etc.

Sounded logical.
Can I add s_1 or s_2 to differentiate which player to use ?
example:

Nadal   1.60    5.00
Nadal   2.50    7.00
Murray 3.20    3.60
Nadal   1.80    7.20
Murray 2.10    5.00

s_1_bm_1_backa       =   7.20
s_2_bm_2_backa       =   3.60
where s_1 equals Nadal and s_2 equals Murray.  
Thanks Mark.

Hi
Yes that will work fine.
