How to simulate high tick rate for indicator testing?

[MiCe1999]

I upgraded to 8.4.1 yesterday. Also yesterday I experienced very high chart lag. I'm not sure if this is due to the upgrade or indicator and need to do more testing.

Is there a way to simulate high tick rate for testing on NT8 platform?

Have you tried using Market Replay (aka Playback Connection) at high speed?

Market Replay updates every second therefore I assume it's not a proper test.

Not sure what you mean.

On high speed settings, on a tick-based chart, Market Replay sure
seems to update the charts a lot faster that once a second.

Have you tried it?

Hello MiCe1999,

The playback engine runs at 1 second intervals to pump in data however all data events are recorded so it would still execute code/bartypes in the same way. You could still use that to simulate high tick rates. An example would be testing a renko series which can impact performance, in times of high volatility you could see many bars created in a very short time, the bar type will still have to do the same calculation as it does in realtime and build each bar causing a load on the system. Playback would be the only mode besides the simulated data feed to execute the strategy in realtime as a test, the simulated data feed does not provide a way to simulate high volatility but instead uses a slider control to increase or decrease the price over time.
