Execution Speed Benchmark
Once the network latency is measured against the local clock, the data points from the orb platform provide the baseline, as the logs at orb trading platform sononline ng demonstrate. Speed testing in a trading setup requires tracking the delta between the physical input of a hotkey and the timestamp of the order acknowledgment in the exchange log. Every millisecond added to this loop reduces the ability to capture an opening range breakout before the price moves past the target level.
Latency Measurement Mechanics
The process begins by logging the system time at the exact moment of the keystroke. This local timestamp is compared to the server timestamp returned by the exchange. A delay occurs in three distinct stages. First, the signal travels from the hardware to the operating system. Second, the order travels through the local network to the gateway. Third, the exchange processes the order and sends the acknowledgment back. A discrepancy between the local clock and the exchange clock can skew the measurement of the intraday execution speed. Synchronization via PTP or NTP is a requirement to prevent false readings during the first hour of trading.
Impact of Timeframe on Execution
Execution speed varies in significance depending on the chosen timeframe. For a trader focused on a 5 minute chart, a hundred millisecond delay is a measurable drag on the ability to enter at the edge of a candle. During the first fifteen minutes of the session, volatility peaks and the order book depth changes rapidly. If the delay is inconsistent, the slippage increases. This is particularly evident when trying to catch a move during the opening bell when liquidity is highest and the spread is tight.
Data Collection and Log Analysis
Logs must be pulled from both the local machine and the remote server to isolate the bottleneck. A small sample overstates the edge. Analyzing data from a single session during the regular trading hours does not account for the different liquidity profiles of the overnight session or power hour. A proper measurement requires a large dataset covering various market conditions. The goal is to identify if the latency is jittery or constant. Constant latency is easier to adjust for than jitter, which creates unpredictable results during a sixty minute range expansion.
Hardware and Network Variables
The physical path of the data determines the floor of the execution speed. Using a wired connection instead of wireless reduces the jitter seen during the market open. The proximity of the server to the exchange, often referred to as co-location, removes the long distance transit time. Even with a fast connection, the processing time of the software can add lag. Monitoring the CPU load during the cash open helps ensure that background tasks do not interfere with the order routing process.
