Thanks for the input, the suggestion only spoke to the diversity of faction relations(aka i get this product from X faction but the price of Y faction's product is better right now, i could reach out to them and start doing deals so I don't only sell X's product). I think this would promote RP in the long run, products spreading more widely and alliances made through the economy, not just petty feuds and egos.
That being said I get what you're saying about employed people and people on different timezones (I am both of those things) and how they might not have the time to diversify but if you think about it, the current system isn't doing those people any favor either since it's completely random if the price is gonna be good when they can play the game. Using suggestion #1 would let those people get an idea of the current market, and if they've diversified their trade beforehand they have more of a chance to get a better profit. At least that's my opinion!
That is true, there could be delays to the price changes added to give people a chance to "abuse" the market, but even if there isn't and the price fluctuation is somehow instant(which i don't believe would be the case) the person selling large amounts at a time is directly hurting his own profits by flooding the market with the product he's selling.
Either way thanks for your time in replying to this, there's definitely flaws to it but it could lead to something good with the input of the community!
