comment How to become a registered market maker on an exchange
If you're seriously considering becoming a registered market maker, you should be talking to the exchange where you want to register. They will happily tell you the answers. Not on topic for this forum, IMO.

comment Recreate Positions after downtime. Suggestions requested
I will add, it also depends on who you're interfacing with and the supported order entry port features. For example, OUCH ports can cancel all open orders on disconnect. Trying to preserve open orders across unexpected system failure is likely not going to work very well.

This isn't really a question anyone but you can answer because it depends on how you've built your system.

Define "outstanding" positions. You said you can look at your execution log to determine fills. From fills you can build positions, so I assume you mean something else. Do you mean, "pending orders" ?

comment Forcing price to rise or fall by high volume buying and shorting
I don't think so. Spot FX is not regulated as far as I know. Your counter parties / ECN might not like it though.
