For the spot market, you can run multiple bots on one trading pair. Each bot will only consider its own orders.
For a futures market with a one-way position mode, launching multiple bots on the same pair is undesirable, since none of the bots will be able to control the position.
For the futures market with the hedge position mode, you can run 2 bots simultaneously in the same pair with different algorithms (LONG and SHORT). Each such bot will have its own position (independent of each other LONG AND SHORT positions, respectively).
