Was just checking on SE to see who is suppressing the price of ENG (probs the guys who mine it) and saw your trading bot in full action. Noice work!
How does your bot handle loss? In a scenario, where you have bought X for Y, but before you manage to sell it for Y+1, the price drops rapidly much lower. Will it sell the tokens for loss or hold the higher selling price?
The orders will stay up indefinitely, since the bot renews all orders. if the price falls the bot will create orders all the way down. It'll stay at a loss until the orders get filled. However i only use the long feature on coins that have potential to move upwards and I use the short feature on all the coins that I mine with my miners(or in game currency that I earn from various steem games). So on many markets I make money if the coin goes up or down, doesn't matter really.
