CANCELLED_NOT_PLACED

[gvigliani]

Hi Gary , Good morning.
I have a problem that is bugging me.
I make a first play:
preBet_ref = ba.placebet((GreenFav(GF) - 1), "L", oddcom, StakExcg, True)

Perfectly executed.
When executing the next which involves only changing the "B" values, oddcom and StakeExcg give me the Canceled_not_Placed error.
What am I doing wrong ?

Thank you

CANCELLED_NOT_PLACED comes from an update request. It means it cancelled the bet, but could not place the new bet. You must be placing a below minimum stake bet to get this error.

eg. odds: 1.1, stake £0.90

1. Lay bet of £1 at 1.01 is placed
2. £0.10 is cancelled leaving a lay bet for £0.90 at 1.01
3. The odds are updated to 1.1. Betfair actually cancel the bet and place a new bet at 1.1. The bet placement part is failing, but I don't know why.

Have you checked if the odds and stake are acceptable? Can you give examples of exact stakes and odds used?
