Candle Refresh rate

[kimboox44]

Hi, the platform is solid i was wondering why the candle chart (last candle) is moving slow, while that candle behaviour is very critical for momentum traders, it updates at best 2 to 3 times per second where 100s of quotes went in between. is that a technical limitation, i think traders choose eSignal for that low latency candle refresh rate.

i can see you're using FlexChart api with maybe the Animation property.  or teechart for charting. is there any chance of increasing the refresh rate.

we do not use FlexChart. We have very customized teeChart stuff. Anyway, the refresh is done by us, not the component. Update speed will vary depending on the load - # of charts, etc. if there was no update and a new update comes in, the chart will be updated right away. If you have high volume stuff where there is a continuous stream of quotes, lets say 100s of times a sec, the chart will be updated 4 to 5 times per sec.  Quotes on the portfolio get updated more frequently.

i like the platform as momentum trader, if only there was a way to increase that refresh rate to a maximum by settings (for ones who can handle the resources needed). can we have like a real time updates in settings as an option (disabled by default). i think a lot of traders use price action behaviour in trading. specially momentum traders. (people pay $170 for esignal just for that, nothing else)

Thank you.

I've made some changes to see how it impacts things. Seems OK at least when I tested with just a couple charts. email support - I will give you a version that has the change

[kimboox44]

thank you, i wasn't expecting that, but the problem i'm using Medved white labeled... so i don't know how to proceed, again i really appreciate your help.

[Jerry Medved]

Yes I know. Email us I'll get you the update for that as well

[kimboox44]

Thank you, it's working great, i've some remarks if you want to take a look, (they don't bother me).

- When you open intraday chart, i can see that you split the loading into current bar and back fill, and sometimes the last candle has wrong open because quotes are not available in histrocal and that quote is gone by the time the chart is open. check image bellow, (a solution maybe refill last candle after 60sec or whatever timeframe to replace that messed up candle when new one open)

- Is it possible to have LULD calculated in L2

Again they don't bother me, just letting you know

what you are seeing is if you enter a symbol in the chart that is not already getting quotes in portfolio. MT starts the quotes and request backfill. that candle is where the data is merged. Do you see this only with OHLC backfill or if you set the default to be TICK backfill?

LULD on L II - will have to see. we have it implemented as an indicator on the charts currently

Hello,

will the faster candle refresh rate function be added in a new beta version?

[Jerry Medved]

you can add /FASTCHARTS commandline parameter to the MT shortcut to set it now. It is in production. I just wanted to wait and see about performance impact before changing stuff in the UI 

[TheRefik]

Thank you, it feels so much better.

 

May I ask, is it updating on every quote it recieves, or is there a limit on how much it updates per second?

[Jerry Medved]

chart update is triggered by a received quote (vs polling) but there is a max. That max is dynamically determined based on your chart speed settings (in settings) as well as load on the system. We did just tweak stuff to make symbol switching dramatically faster. Will be in next update.
