Do you know any technics that can be effective enough against such an attack in a MMA ring? And also
do you know any technic that is good enough against this in a fight on the streets assuming you are NOT in the position to use any weapons, tools, and you can't call for help.
thanks in advance

Answer Which 'wicked trick' are you talking about? The chi na-like diving forward roll, scissoring leg trap and takedown? Or the broken ankle she got for handing the other woman her leg by misjudging the distance and attacking too close?
The former is move (as in anytime something that looks weird is coming at you, get off line before you find out what it is). Backpedaling is often less effective, but it can work too. Generally speaking -- especially in non-sports context (a.k.a. real violence) you don't want to charge into anything you don't know or expect.
The second is once you've handed someone your foot like that, you're pretty well screwed if they know how to attack other than with punches and kicks (i.e. twist the ankle until it breaks). She wasn't fighting to escape (which might have given her a chance to save her ankle), she was still there trying to engage. This left her vulnerable to the ankle break.
As for the last question, "Yeah, learn to run away." Or if that term sticks in your craw, learn when to apply a 'strategic withdrawal." One of the biggest differences between 'fighting' and survival, is that in fighting, you are always pressing forward to overwhelm your opponent. This often creates physics that allow nasty things to happen to your body. Whereas if you learn to say 'Oops, this offensive isn't going right, time to pull back' you'd be amazed at how much damage you avoid taking. It is common among Western fighters that when a technique starts going wrong to keep on pushing forward in order to force the technique. That is also a common sports based attitude. Another common problem is doing a move that you are 100% committed to and are stuck with no matter what. Notice that the woman who did the bad chi na take down was pretty well stuck on the ground.
While she could have tried to break away -- which she did do after she realized the other woman had her ankle -- by that time it was too late. But again, the sport minded mindset of fighting, kept her there trying to 'win' instead of withdrawing from a tactically unsound situation. Don't be afraid to break contact and continue mission if something isn't working out for you.
