Advanced Order Types in Dark Pools
Dark pools support sophisticated order types beyond simple market and limit orders. One such type is the pegged-to-midpoint order. This order type allows an institution to post an order that is pegged to the midpoint of the NBBO. For example, if the NBBO for NQ is 3900.25 x 3900.50, a midpoint order would be pegged at 3900.375. This allows the institution to capture the spread, resulting in significant savings on large orders. A 1,000 contract order on NQ would save $125 per tick.
Another advanced order type is the discretionary order. This order type allows an institution to specify a discretionary price range. The order will execute at any price within this range, but it will only be displayed at the primary price. For example, an institution could place a discretionary order to buy 100,000 shares of SPY with a primary price of $450.00 and a discretionary range of up to $450.10. This allows the institution to be more aggressive in seeking liquidity without revealing its full intentions to the market.
Iceberg orders are also commonly used in dark pools. These orders only display a small portion of the total order size. For example, an institution could place an iceberg order to sell 1,000,000 shares of CL with a displayed size of only 10,000 shares. This allows the institution to sell a large position without putting downward pressure on the price. The hidden portion of the order is only revealed as the displayed portion is executed.
The Role of Algorithms in Dark Pool Trading
Algorithms play a critical role in dark pool trading. Institutions use sophisticated algorithms to break up large orders into smaller pieces and execute them across multiple dark pools and public exchanges. These algorithms are designed to minimize market impact and achieve the best possible execution price. For example, a volume-weighted average price (VWAP) algorithm will attempt to execute an order at the VWAP for the day.
Algorithms are also used to sniff out liquidity in dark pools. Some algorithms will send out small "ping" orders to multiple dark pools to see if there is any interest in a particular stock. If a ping order is executed, the algorithm will then send a larger order to that dark pool. This allows institutions to find hidden liquidity without revealing their intentions to the market.
However, algorithms can also be used for predatory purposes. Some high-frequency trading firms use algorithms to detect large orders in dark pools and trade ahead of them. This is known as "front-running." To combat this, dark pools have implemented anti-front-running measures, such as randomization of order execution and time delays.
Worked Trade Example: Fading a Dark Pool Print in GC
A large dark pool print can often act as a support or resistance level. If a stock trades below a large dark pool buy print, it can be a sign that the buyers have been exhausted and the stock is likely to trade lower. A trader could use this information to enter a short position.
- Entry: A trader could enter a short position in GC at $2300.00, just below a large dark pool buy print at $2301.00.
- Stop: A stop-loss could be placed at $2302.00, just above the dark pool print level.
- Target: A profit target could be set at $2295.00, which represents a reasonable move for the commodity.
- Risk/Reward: The risk on the trade is $2.00 per contract, and the potential reward is $5.00 per contract. This represents a risk-to-reward ratio of 1:2.5.
When Fading Dark Pool Prints Fails
Fading a dark pool print is not a foolproof strategy. A large dark pool print can also act as a magnet, drawing the price back to that level. If a stock trades below a large dark pool buy print, it could be a sign that the buyers are simply reloading and are waiting for a better price. In this case, the stock could quickly reverse and trade back above the print level.
It is also important to consider the context of the market. If the overall market is bullish, fading a dark pool buy print is a low-probability trade. It is better to wait for a bearish market environment before attempting to fade a dark pool print.
Finally, it is important to use other indicators to confirm a short entry. For example, a trader could look for a bearish candlestick pattern or a moving average crossover to confirm a short entry. Without confirmation from other indicators, fading a dark pool print is a risky proposition.
