Hi,

Is it possible to set the data be automatically flushed into database after the task finished in the Historical Data Download Scheduler please?

Thanks.

ragdoll

Is it possible for multicharts to auto flush cache into database when the CPU utility is low?

Hi,

Yes, the data downloaded by Historical Data Download Scheduler is first stored in cache.

ragdoll

So that means the Historical Data Download Scheduler will cache the data in memory. You must claim it clearly. Hello, You can force the historical data to be saved into the data base without closing MultiCharts and all its processes, To do that please go to MultiCharts > File > Flush Cached Data to ...

Hi,

Every time I open Multicharts, there is a pop-up saying "Unable to create AvaTrade plug-in: corresponding COM component does not exist or cannot be loaded." I am not using AvaTrade. Is there anything I can do to disable this pop-up please?

Thanks.

Is the data from Historical Data Download Scheduler cached? So that after the scheduled task, the multicharts needs to be closed to have all grabbed data flush to database?

ragdoll

But most users keep Multicharts open 24 hours, is it possible to flush the cache to DB automatically? In my case, the multicharts will be closed only when windows enforced update restart so that multicharts have no chance to flush its cache. Hello ragdoll, Once data is downloaded from the data feed ...

I found there are only several days per months got data written into DB, although the scheduled task run everyday and the log told me everything goes well. Is the data grabbed by the scheduled task cached or directly written into the DB? Do I need to switch to file cache as the following link? https...

ragdoll

I run historical data download scheduler everyday night and in the next morning to check if it were completed by logs. Everything looks good until today I checked the data in database by edit data. I found there are a lot of data not in the database. Even there are only three days in a month having ...

In Quote manage, I want to change the setting source to symbol dictionary for multiple symbols. How to do it in a batch please?

Thanks.

ragdoll

Note: Restart of all MultiCharts Processes is required to apply the changes in the Symbol Dictionary.

ragdoll

It could be still reproduced. 1. Add the "MCA" root of interactive broker into the symbol dictionary 2. Restart the Quote Manager to make sure it works 3. When the Quote Manager is open, restart the windows (As windows 10 usually try to restart itself to finish some update work) 4. After logging bac...

ragdoll

Yes, that is what I expect MC to do. However, I am sure years of data got stored in DB but MC still needs to backfilling from start. Thanks. Hello ragdoll, Once data is downloaded from the data feed server and plotted on the chart, it is stored in the cache. When you close MultiCharts, QuoteManager ...

ragdoll

The name is just “MCA”.

Hi ragdoll ,

Please make sure you are not using unsupported symbols in the Symbol Root's name (like <;> <:> <=> <!>, etc.).
If you don't, and the issue is still reproduced, please come to the live chat Monday-Friday from 5:30 AM till 12:00 PM ET to demonstrate it.

ragdoll

Sometimes my PC got crashed and restart without exiting multicharts first. I found if I restart multicharts then, all charts kept on backfilling from interactive broker instead of database which costs a lot of time. Usually it costs a lot of time to establishing a data connection. As I have all data...

ragdoll

Hi,

I try to add an interactive broker symbol root of MCA on HKFE. And I am ensured I have added into the symbol dictionary and taken effect. However, if I close and open again, the MCA root got disappeared. Anybody can help here?

Thanks.

ragdoll

If there is some historical data in ASCII and continuous real time future update by data vendor, how to combine them together please? Thanks.

ragdoll

Would you please help to explain how multi charts parse the name please?

Hi ragdoll,

It won't have any negative effect on your custom futures, that's the correct solution.

ragdoll

Hi, I have a expired future contract HSIZ7 which got expired in 2017 December. However, Multicharts thought it will be expired in 2027. I checked there is a solution by just modifying the contract name to HSIZ17. However, as some customized future depends on it, will there any side effect on it plea...

ragdoll

Hi,

The expiration date for future MCA on HKFE is wrong. Anyway to fix it please?

Thanks.

In the strategy property form, say I set the initial capital as x and the strategy will trade on some future contract.

If you need a 5-day MA of daily closes, then: var: sma(0,data2); sma=average(close,5) data(2); If I do this, seems it still needs MaxBarsBack to be set to 600. This is a known (and very annoying) "feature" of MC. Assuming you want to calculate a 600-bar average of 3-min bars, then the walk-arounds c...

Hi,

I learned how to draw an arrow up or down to a bar by Arw_New. However, I saw there is an arrow just left to the bar when there is an entry order or exit order. May I ask how to draw that kind of arrow by programming please?

Thanks.

Hi, In my study, there are 3-min bars for data1 and daily bars for data2. One daily bar corresponds to 120 3-min bars. If I want to get the 5-day moving average, what MaxBarsBack should I set? 5 or 600? If I set it to 600, then seems both data series share the same MaxBarsBack and the study starts a...

ragdoll

Thanks so much. May I ask if I have to place fastest data as data1 in current MC version please? Sometimes the data is added after several rounds of development which makes the refactor difficult. Thanks. If the fast data series is Data1 and the slow data series is Data2, then you can add a conditio...

ragdoll

Hi, I have read the FAQ about multi data and tried to do some program. My guess is the Multicharts engine will evaluate each bar of the fastest data series. May I ask if there is any keywords of the language to have the script run only one calculation of each bar of slower data series please? Thanks.

MC support provided the following answer via online chat: In auto trading Price orders are valid at broker while they are sent by the strategy. That means the conditions for order generation should be met in your code on each bar close or each tick (if IOG=ON) calculation while you need to keep your...

Say I made an entry order and manually place stop order per bar as follows. if condition then buy 1 order at next bar on some_price limit; if marketposition = 1 then begin stop_price = some new stop price based on market; sell 1 order at next bar on stop_price stop; end; If the stop order not filled...

ragdoll

For my understanding, if the order is sent out to broker however not filled and the condition is not valid anymore. MC will send a cancellation command to broker, right?

ragdoll

In this case, the behaviour of the simulation is not in line with the active trade. How can I rely on the results of simulation? Thanks.

ragdoll

An order is executed at the point specified by the parameters; if the order is not filled within the specified bar, the order is cancelled. I understand the above logic when in back test. However, I wonder what's the behavior of the buy/sell order when it is sent to broker. Is the order sent out to...

Hi Ragdoll,

Not exactly scrolling sync as you ask, but FWIW you can already use the following option: Menu > View >Tracking Settings > Tracking Time
Then when you click on a chart, every other opened chart will scroll to the same cursor date/time.

Per my test, values of variables in a function will be kept no matter the function is type of simple or series. I define a simple function as follows which name is "test". variables: index(0); index = index + 1; fn_test = index; And in an indicator I plot this function through all bars. Plot1(test()...

Sometimes we need to compare two strategies in two windows. Is there a way that we could scroll in one window and the other window will be automatically scrolled which would be more convenient for the comparison?

Thanks for reply. I also tried assign that lowest function to a variable but with same result.

Why are you not assigning the lowest function to a variable?
