IB's MidPrice vs Adaptive Algo

[d08]

Does midprice work for futures and options?
Do you need the latest version of TWS to use the algos?
Are there additional charges for using algos to execute
Does midprice react differently when market is moving extremely fast vs slow

I'm using build 979.4, not sure about each and every version.
There's no additional charges.
Obviously in a fast market when asks are being hit, there won't be many mid fills.

In other words it wouldn't be wise to use midprice during the first 15 minutes after the market opens, correct?
