In 5.2 version there will be PRICE LIMITS based on Markets ticker data. That limits are dynamics and try to follow a trend.
I'm just testing these code today (i needed to change a lot of things in Limit price panel).
Then there is another 1 function i need to add and then i'll be ready for 5.2 BETA Version.
This is extremely interesting. I am tempted to ask you to release v5.2 without the other feature you are thinking and add it to v5.3!
