# Pair processing

How trading pair cycle in Gunbot

**Pair processing example for 1 exchange:**

* 2 enabled trading pairs
* Exchange delay set to 5
* "Processing" below means that Gunbot retrieves data and trades when strategy trading conditions happen in that round
* First round of pair 1 is processed
* Waits 5 seconds (as defined in the exchange delay)
* First round of pair 2 is processed
* Waits 5 seconds
* Second round of pair 1 is processed
* Waits 5 seconds
* Second round of pair 2 is processed.
* ... continues cycling through further rounds

**Parallel processing of multiple exchanges**

If you have trading pairs across multiple exchanges, each exchange will process pairs in parallel. This means that a pair on exchange 1 does not wait for pairs on exchange 2 to be processed first.

Every exchange will individually cycle through enabled pairs like described above. Each exchange can have it's individual delay setting.
