I would love to see a bot take advantage of price corrections. Every time I've seen a huge run in price, it is always corrected about halfway down (number off the top of my head).
For example, NEO (formally ANS). I bought in at $12, and in the past week or two we've seen it make a huge leap to $50. Today, it's at $34 which is the correction. While watching the graph hit $50, I knew I should have sold and waited for this current price to buy again. In fact, I've seen this happen to every single coin that I've ever held. It makes that initial jump, then the price corrects. If a bot could be coded to watch for a new ATH (all time high), and then sell when it has dropped 5% under that ATH (this is when people tend to panic and sell of everything, which causes the bigger drop) I believe it would be very profitable. Then if the bot were to wait a few days for the price to stabilize, and buy in again it would maximize the traders profits!
This is the basics of the assets world. Every asset born, develop, stabilize and downward. The point is to predict each movement before it happens and this is not easy for sure.
