Trade Strategy (Kebir Blue)

What would be a good trade strategy for selling? I tried doing this:

When the products are put on the market, trail quality by: 10
For each month that the products are not sold, decrease the price by: 8

I did this and some of my corporations got the red "Too High". Anyone know a good trade strategy?

If some product is in over-supply (ie. green) then even if you offered at cost price or below it would not sell immediately and so your corp would show 'too high'.
Rule of thumb-ish, add 10% of the quality you produce to your selling price, so a 200Q product, offer at 220, 250Q at 275 etc. Time based strategy with a decrease monthly of 10%.
More aggressive strategies can work, like 60 over Q produced, 20% drop monthly, it's up to you to play with it, and this strategy would generally only be good for products that are more often in high demand (ie. red).

Crafty.

i like 60 - 20

as for the coprs who don't sell

if they die . . . they die.
