Is there ANY difference between these two events?
Thanks. Dale |

OnPriceChanged event frequency is limited on client to reduce GUI CPU overhead.
the difference is seen mostly in peak hours. |

Hmm... That seems to disagree with a prior post you made:
1: Subscribe for price updates calling OECClient.Subscribe and handle OnPriceChanged or OnPriceTick - both events are called when last price or any price information (such as best bid/ask) is changed. However, these updates will not occur more than 20 times per second. I knew I could SubscribeTicks and handle OnTicksReceived to get every tick. Are you saying I could also Subscribe() and handle OnPriceTick to get every tick? That would be great! Thanks, Dale Dale |

No, it is exactly same as I posted previously: OnPriceTick is called on change of last price or bid/ask prices and it could be called more often than OnPriceChanged, but it does not guarantee to give every tick.
The only way to get every tick is SubscribeTicks/ OnTicksReceived. Edited by SergeK on Oct 30, 2007 at 01:30 PM |
