When I load a signal on a lets say 10 year 5 min data chart and then i change the Data Range (start date) from lets say 2004 to 2005 then it takes forever to see the new results. To overcome that problem I make the Status OFF and then ON again in The Signal and then the results appear fast.
So how can you improve MC that when I change the data range settings in a chart the results of the signal appear faster ?

Hello amadeu1,
- Are you sure there is no "Backfilling..." in the left top corner of the chart?
- Do you use Bar Magnifier?
- Do you use Extended Backtesting mode?
Re: Change of data range in chart -- results are displayed v
There is a backflilling .... on the chart but it takes forever. However while backfilling when i make the status OFF and ON again the backfilling etc goes much much faster. So some error there i think
I dont use Bar Mgnifier or extended backtesting

The status of an indicator/signal should not affect the speed of receiving/processing/displaying quotes. I also tested and did not see what you described. Are you able to reproduce the scenario in 100% of cases?There is a backflilling .... on the chart but it takes forever.

Re: Change of data range in chart -- results are displayed v
Sorry for the late reply but i was on vacation.
I went back and looked at what exactly happens:
Lets say you have two different session templates (one 08:00-12:00 and another 08:00 - 14:00)
I load a 8 year 5 minute chart and apply a signal and the first session template. This goes reasonably fast.
Then I change the session template in the chart to the second session template. I see then the backfilling.... in the left upper corner. But it takes a very long time until the buy and sell signals appear from the signal. Its much faster while it shows the "backfilling..." to make the status of the signal OFF and ON again.
Why is that ?

If the issue still persists, please come to our live chat during working hours (6:30 am – 2:45 pm EST) to let our operators connect to your computer remotely and study the case.
Re: Change of data range in chart -- results are displayed v
I found out now that this happens only when i use markets where I use asccii Mapping in the QuoteManager. If i use markets where i import the data in a symbol (in quote manager) then it does not do that
Thanks
Thanks

ASCII mapping = data is not stored in MC database, it is in the ASCII files and it takes time to reload it into MC chart.
ASCII import = data is imported into and stored in MC database, it is plotted on chart much faster.

Re: Change of data range in chart -- results are displayed v
I do understand that -- but its still funny that the reload takes forever - but when i set the system to OFF from ON and then back to ON then it loads the data much faster
Anyways -- in another thread i asked whether i could do bulk import of ascii data into many symbols in quote manager - is there any way ?

Re: Change of data range in chart -- results are displayed v
As i mentioned previously switching status of an indicator/signal from off to on should not affect the speed of receiving/processing/displaying quotes. If it does and you can easily reproduce it, please come to our live chat to demonstrate the behavior.I do understand that -- but its still funny that the reload takes forever - but when i set the system to OFF from ON and then back to ON then it loads the data much faster
Unfortunately at the moment there is now way to import multiple files, it is possible only with ASCII mapping.Anyways -- in another thread i asked whether i could do bulk import of ascii data into many symbols in quote manager - is there any way ?
