Hello!
I'm sorry that I've overlooked your topic, and I'd like to reply anyway.
What's the best way to run multiple strategies?
That depends on the strategies: if, say, one is for backing in football and another one for laying on horses, then there should be no problems. However, if you are looking to run two staking plans in the same set of markets, this generally wouldn't be possible, unless some tricky math is thrown in, because BetFair keeps all your bets in a single list, without the possibility to distinguish which procedure (trigger, bot, etc.) placed which bet.
What's hedge out options are there?
Manual green-up, including through the Ladder and in the
Engineer Mode, Auto-Greenup and
trading out using triggers.

10 Facts About Green-up in MarketFeeder ProWhy do some bets not get placed, giving an error for "invalid price or stake"?
For instance, twice today a trigger has tried to lay at 4.5 for £4 liability and given that error.
It means you intended the price to be 4.5 and liability 4, but something went wrong. For example, you did not have enough funds, or you did not turn on "Allow small bets" in Betting Options and your bet was below the allowed minimum, or the market got suspended, or the price/amount weren't really 4.5 and 4. To find out what's wrong, check the
Program Log for any obvious problems, and then the log of the trigger itself.
