can we use the in-house exchange price for that? Or something like:

Never sell under Conversion rate HDB into Hive with the 3,5 days average?

For example Hive is 0,50$.

2 Hive 1HDB conversion and this is the stop level. So Hive would be never bought from the market under these levels.

Only if we become 2.05 Hive as a minimum for example.
