Only a complete moron would put a stop loss order on a $.000x stock.
I think the buy-painter is trying to keep the price looking better and the sell-painter is hoping to force someone to buy his shares at the higher price.
Retail shareholders rarely want to spend a $10 commission to trade $5 worth of stock or have enough shares to care whether the price is at $0002 or $.0003. I think you'll find most painters are pros.
