I may be way off on this but here goes my not so educated guess

1. current offer price is .50
2. Bot 7 sells 7 parcels at 0.495
3. This temporary forces the current offer price down to 0.495
4. This triggers some stop losts and some stocks are then sold at 0.495 hence keeping the current price at 0.95
5. Bot 7 sells another 7 parcels at 0.490
6. This then triggers the stop losts at 0.490

and so on ...

This is a semi accurate high level look at it or am I way off?
