The last time you got a bad fill on a Bank Nifty weekly, you probably weren’t able to figure out whose fault it was. Was it the WiFi? Your broker’s servers? Or the market itself? Every trading app in India claims to be fast. But almost none gives you the data upfront.
Recently, Sahi published its order execution speed data for 9 million trades. And the biggest takeaway was P95 of 6.61ms across 9,089,472 real orders placed between March 13 and 30, 2026. That means 95% of those orders were executed within 6.61 milliseconds. We’ll explore what that means and what it doesn’t.
Key Takeaway
- P95 of 6.61ms order execution speed for ~9.09 million real orders.
- The scope is server-to-exchange, not your device to the exchange.
- Every hop is broken out on a public dashboard you can audit.
- Sahi is the first for Indian retail brokers to self-publish order latency.
Sahi Discloses 6.61ms P95 Order Execution Speed Across 9 Million Orders
A P95 is the time it takes for 95% of your orders to hit the engine. So about 8.6 million of the 9.09 million reached the exchange from Sahi’s servers in under 6.61ms. The mean was near 5.92ms – that’s really quick.
On the record:
- P95 of 6.61ms order execution speed, the headline on the public dashboard.
- A live two-week window for ~9.09 million real orders.
- Daily P95 held between 5.95ms and 7.77ms, volatile sessions included.
A mean hides your worst orders. But a P95 is the honest way to quote order latency.
Why Sahi’s Public Order Latency Disclosure Stands Out
The number’s interesting. But what’s more important is that anyone can read it.
No other Indian retail broker publishes its own full order book like this: every order, every hop, as a percentile, open to anyone. Others measure speed, just differently:
- Third-party testers exist. Tools like AlgoTest’s Broker Speedtest probe broker APIs from outside every 15 minutes. That’s an external sample, not the broker’s own data.
- Most brokers just say they’re fast without sharing any number. “Ultra-low latency” with no number is just a claim, with no easy way to verify.
- India has no disclosure norm. US brokers file execution-quality reports by mandate. Indian brokers mostly publish nothing.
Rather than just claiming that they’re the fastest, Sahi shared the numbers. Now anyone can look into it
Inside Sahi’s Order Execution Path: EMS to Exchange
The clock starts at Sahi’s Execution Management System (EMS) and stops at the exchange. Every hop between is timed.
| Stage | Mean latency |
| EMS and network to OMS | 4.28 ms |
| RMS risk check | 0.20 ms |
| Network to exchange | 1.45 ms |
| End to end (mean) | 5.92 ms |
| End to end (P95) | 6.61 ms |
Source: Sahi execution data, Mar 13-30, 2026.
Note: The hop means add up to 5.92ms. The 6.61ms is the P95 of the whole trip, not a sum of hops. Percentiles do not add.
What the 6.61ms Figure Leaves Out
The clock doesn’t start on a whistle. The trip from your phone, across your network, to Sahi’s servers is out of scope, so the 6.61ms is server-to-exchange. This is the leg a broker controls.
What This Trading Platform Speed Data Means for Sahi App Users
Of course, trading platform speed isn’t just about impressive numbers. On any trading app, any drop in trading speed shows up as slippage. Slow placement means the premium you tapped isn’t the premium you get.
- Faster, steadier placement means tighter slippage on fast weeklies.
- A published percentile shows how the platform behaves on a bad day, not just its best tick.
- Speed needs stability.
And Sahi reported no technical glitches to the NSE from December 2025 onwards. That’s an achievement, especially since even large brokers have experienced technical disruptions.
The milliseconds are not the point
A latency number you can pick apart order by order is a different claim than one you’re told to trust. Judge it against your own fills first. Stats aren’t what you should entirely rely on.
Educational only, not investment advice. F&O carries real risk of loss. Figures cover Mar 13-30, 2026 and can change.
FAQs
How fast is Sahi’s order execution speed?

No. Your device-to-server leg is out of scope, so your experience also depends on your own network.
