Sokolova's actions are consistent with the Standard relating to priority of transactions because:

1. Pro-rata allocation: She allocated IPO shares on a pro-rata order basis to all clients, which is fair and equitable
2. Sister as client: Her sister is a regular fee-paying client, so including her in the allocation is appropriate
3. Disclosure frequency: While disclosure frequency could be improved, the Standard doesn't specify exact frequency requirements
4. No self-dealing: She didn't prioritize her own transactions over clients'

The key is that she treated all clients equally in the allocation process.
