Im looking for a a planet neg. script that only sells to the port an amount that you choose, not 100% of the product.

If you have mombot there is a built in script call Merch.

I havent seen one. The mombot merch sells 100% of the product if it can.

botname merch 2000 o e neg

it does a cim and gets a list of ports that have at least 2000 of the product

I prefer SupG worldtrade script, lots of options and has never failed me.

I am afraid that I do not remember the threads, but someone asked for an example of reading a file to an array, and I believe that it was Prometheus that gave us the great basis for a planetary trader. I based several scripts off of that and someone filled in the parts and shared his own planetary trader. Running a CIM and visiting all of the 2k+ ports would be a good step, but I have upgraded many ports to the maximum and keep a list, so I just feed it that. It was easy to have it make sure that each port is buying at least 90%. It would just be one more step to make sure that it is also buying at least 2,000.
