Execution Speed
Also known as: order execution time, time-to-fill
What is it?
Execution speed is how quickly your order actually gets filled once it has been submitted to the broker. It is one half of the journey from a trading idea to an open position, and it is easy to confuse with signal latency, which is the other half. Signal latency measures how fast a signal reaches you; execution speed measures how fast the broker turns your resulting order into a real trade. Both legs have to be quick for fast trading to work, because either one can spoil the result on its own. Picture this: a signal reaches your screen in ten milliseconds, brilliantly fast.
But the broker you are using takes eight hundred milliseconds to fill the order. During that almost-one-second pause on a fast move, the price keeps running, and you end up filled well away from the price the signal showed. The lightning-fast signal was wasted by the slow fill. The reverse is just as true: a broker with instant execution cannot help you if the signal took two seconds to arrive. For a trader, this matters because optimising the wrong leg wastes effort.
If your fills are slow, upgrading your signal delivery changes nothing; if your signal delivery is slow, switching brokers for faster fills changes nothing. The fix is to measure the two separately so you know which one is the real bottleneck. On short-target and time-sensitive strategies, where a few pips decide the outcome, both delivery and execution must be fast for the planned entry to survive into a real fill.
Why it matters: Even a fast signal can be undone by slow execution; both legs - delivery and fill - must be quick for short-target trades to work.
Execution speed is the second half of getting in at the intended price; a slow fill negates a fast signal.
Real-world example
A signal arrives in 10 ms, but a broker that takes 800 ms to fill still hands you a worse price on a fast move.
How SignalBots handles it
SignalBots reports both delivery and execution timing so you can see which leg is slow and act on the right one.
Pro tip
Measure delivery latency and execution speed separately; fixing the wrong one wastes effort on an already-fast leg.
Common pitfalls
Optimising signal delivery while ignoring a slow broker fill that is the real bottleneck.
Frequently asked questions
Is execution speed the same as signal latency?
No. Latency is how fast the signal reaches you; execution speed is how fast the broker fills the order once you submit it. Both affect your final price, and either one being slow can spoil a fast trade.
My signals are fast but my entries are still bad - why?
The bottleneck is likely execution speed at the broker, not the signal. A fast signal followed by a slow fill still hands you a worse price on a quick move. Measure both legs separately to find which one is slow.
What slows down execution speed?
A broker's order processing, network distance between you and the broker's servers, account type, and market conditions all play a part. Trading from a server close to the broker, or using a VPS, can shorten the fill time.
Does execution speed matter for swing trading?
Far less than for scalping. On a multi-day trade targeting hundreds of pips, an extra fraction of a second on the fill barely registers. It becomes decisive only on short-target, fast-moving entries.
How can I improve my execution speed?
Use a broker known for fast fills, trade liquid instruments during active hours, and place your trading machine or VPS close to the broker's servers. Just as important, measure delivery and execution separately so you fix the leg that is actually slow.
