BAH64626586 successfully traded over 200 trades against my account, where my bids/asks were only at market value, so only open very short amounts of time.
Another successful strategy played the market, by purchasing early and selling late, after the market had climbed.

Ticker showed long runs at the same last trading price. The volume of these trades is also consistent,
but is probably just the behaviour of the honest bot.
Strategy:
1. Identify long runs of same last price in ticker.
2. Identify who is trading at the these long runs. (open orders and traders against open orders)
3. Which direction are they trading?
4. Identify consecutive runs.
5. Who is trading buy/sell across rising consecutive runs?

Assumptions:
1. Bots like to trade at the same quantities each time.
Profitable trades can be identified from the ticker when correlated with this unique quantity.
2. Order id and timestamps are monotonically increasing.
Orders made at regular intervals provide a correspondence between timestamp ranges
and order id ranges.
3. The most profitable trader is the inside trader.
Givens:

Number of trades per account around price changes.
(2 2 2 2 2 ...) is suspicious.
