Would it give better cover both in case the rice of pair goes up or go down? or I’ll be completely in a wrong track? any opinion on how to cover such a loss risk issue?
Yes you can reduce loss risk by having bots of conflicting interest. For example, I started a leveraged eth grid at 2215. I also have a short bot that will trigger if eth drops to 2186, JUST to cover that trade if the plan goes south. The short is 60% of the value of my long trade so IF the short gets triggered, my losses will not be intensely leveraged. On top of it all, I would close all the bots if eth dropped to 2156 and consider the trade a failure(with minimal losses)
