With sportbetting and stock market you have hedge - reducing risk management.
How would this apply to Roulette?

For example i am risking a bet and not winning, then i should turn around the situautaion and break even or still turn out winning bet but wilth less profit.

John Patrick has a hedge bet for roulette.
He only play low and black.
That way he has a break even situaion and one winning situtaion and 9 numbers against his bet.
So the bet cover 28 numbers.
Have no clue what he use as trigger or differential betting or not.
But is one example of a bet with Hedge qualites.

Other methodology.
Lee Tutor in his book and a member at roulette 30 forum have post a great way to Hedge Betting.

For example you see number 29 hit.
Then you bet high (EC) that 29 will repeat.
If two loses you bet dozen once.
Then if a loss a line bet 3 times more.
If a lose a corner bet and if a lose a street and if a lose split and if a  lose straight up.

Should also add one more that i Think is very common, when you use progression on two dozen, then you hedge betting on zero and accept overall smaller winnings.

Bayes also using Hege betting - reduce risk management.
When he play with his winning method on EC he use diversification.
If i remember it correct he apply it with his MM approch.

Any opinions or suggestions!

Thanks!
