Just asking because I have been developing my trading bot for awhile, I have been successful with it but I'm hoping to learn what you guys are looking for so I will be able to plan what I can do to improve mine and convince you to use it as well.
You are the developer and you should be the one that should think of a bot that people will want. There are different bots for trading and they have different purposes. So you will have to be specific on one. I am not a bit user but I'm exchanges that I am using, they have several bots.
The most important and most difficult feature to implement to a bot would be a way for it to be profitable in all conditions. I am talking about bull market, sideways markets and bear markets.
You know that bots also can not be perfect. Why I see bot useful is because it can make traders to trade 24/7. Bots makes trading easier. It makes the time a trader will spend on trading to reduce as it will be helping the trader to trade.
