Price range for shares in public corps

Most of the time you can sell shares at +-10% of market. Recently I've noticed that in several corps I was limited to sell no higher than market. The change is not applied to all corps and I do not remember reading about any game changes on this.
Here is an example of two corps selling the same product.

There was no change in the way shares are traded for a very long time.

I will have to ask around here, but I think that the price is changing during trading and depending on where the price is at a given moment, the range could change.

If the price already increased in the current trading cycle, the range could be limited on the upside.

The second case looks like it.

Thanks, I think that's it. I just looked at that corp and can sell +10.

I've noticed that C3s don't create orders after the 12th, that's when I've been selling. I guess the prices take a little longer to stabilize.

All automatic orders are generated during the monthly running of all processes. (game month that is).

The servers are faster these days and are done quite quickly.
The slowest one is FB and takes a little longer.

If this means anything to you in terms of opportunities, use them.

Manual share trading keeps going all the time (57 minutes per hour)
and immediate trading of products too.

countries also do not offer or purchase products automatically outside the processing sessions.
