See it running in Sierra Chart
The Chart Tuner Helper overlaid on a live ES chart, with two Performance Monitor windows graphing study time in microseconds and CPU cycles.
Why traders run Power Tools
Whether you’re running a high-speed DOM or just want a chart that doesn’t stutter, Power Tools shows you what’s actually slow — instead of guessing.
Know your real baseline
Measure the true top speed of your charts and DOM before and after you add studies, so you know exactly what you started with.
See what each study costs
Quantify how much update time every study adds. Find the ones dragging you down, then optimize or pull them.
Compare studies head to head
Put any two studies side by side — an OFL volume profile vs. Sierra’s built-in, or two versions of the same tool — in real microseconds and CPU cycles.
Know why a chart feels laggy
Power Tools separates study calculation time from chart redraw time, so you can see why a chart stutters even when the math looks fast.
Tune with numbers, not guesses
Make confident calls on calculation order, update intervals, and study complexity — and learn the real limits of your hardware and Sierra Chart setup.
Numbers you can trust
Built to account for its own measurement overhead, so the timings you act on reflect your charts, not the tool watching them.
What’s included
Two studies. Free. Sierra Chart only.
OFL Performance Measurer
Drop start and end timers around any studies and get microsecond-precision timing plus CPU cycle counts, written to the message log. It keeps detailed logs you can chart over time to spot trends, spikes, and your slowest studies.
OFL Chart Tuner Helper
A live, on-chart readout of study calls and draw-to-chart calls per second, so you can watch performance change as you work. Drag-and-drop positioning, one-click resets, and instant feedback.
Full documentation included — both studies are simple to add. Power Tools is Sierra Chart only and runs alongside any other OFL studies you already use.

Frequently asked
Do I need a credit card?
No. Power Tools is free — we never ask for payment to get started.
When will I get my access email?
Right after you submit the form. If it doesn't arrive in a few minutes, check your spam folder, or email support@orderflowlabs.com.
Which trading platforms are supported?
Power Tools is built for Sierra Chart only. OFL Performance Measurer and OFL Chart Tuner Helper monitor Sierra Chart itself, so there are no versions for other platforms.
What do the two studies do?
OFL Performance Measurer times any study to the microsecond, with CPU cycle counts, so you can see where Sierra Chart spends its time. OFL Chart Tuner Helper shows live study and draw-to-chart call rates right on your chart, so you can find and fix the settings that slow it down.
Can I compare two studies head to head?
Yes. Put any two studies side by side — an OFL study vs. Sierra Chart's built-in version, or two versions of the same tool — and compare them in real microseconds and CPU cycles.
Does measuring performance slow my charts down?
Barely. Power Tools is built to account for its own measurement overhead, so the timings you act on reflect your charts — not the tool watching them.
Can I use Power Tools with other OFL studies?
Yes. Power Tools runs alongside the free tier and Premium studies. If you want the full toolkit, head to our pricing page.
