Green/Red Up Football

[StellaBot]

Hi
Any help here please

I have been building automation for football.
Mainly Over/Under markets.
What puzzles me
When using greening up trigger for 3 times every 5 seconds
ALL OK

However
Red up nope
1.First bet fired may not be matched
2 nd bet fired may not be matched
3rd bet fired may not be matched

The red ups above , because of delay in placing bet will not get matched
EDIT(The price moves away before end of delay)
so potentially have 3 unmatched bets but leaving high risk if fully automated

If red up is fill or kill x 3 , surely the same outcome?

Have I missed something basic?
