Discussion of article "Why Virtual Hosting On The MetaTrader 4 And MetaTrader 5 Is Better Than Usual VPS" - page 13

 
Wahoo:
There's another free monthly tariff on the screen. Why couldn't it be selected?
The broker does not have this service, I think.

Because it is a potential opportunity that is visible but unavailable.

The buttons are grey. If there was an option available, the button would be active.

In the next builds, we will include a mode where the broker can subsidise hosting for active clients.

 

hi 10usd/month for how account can setup? is only 1 account?

can i use vps hosting for several accounts with pay only 10usd?

 
Renat:

Still, how to optimise calculations for VPS hosting?

We have a resource-intensive calculation, limited the calculation from 5000 bars to 1000 inside the indicator itself, limited the call on each tick (calculation once per bar, TF M15).

All the same, every bar the machine will howl for a couple of minutes and then quiet down until a new bar.

How not to fall into the trap of resource limitation? How to spread the task over the whole bar evenly? (in this case it is not essential whether the refining calculation will be made at the beginning of the bar or during the whole bar drawing time).

ZY Again, the task is essentially parallel, and parallelisation mechanisms in mql are scarce, and those that exist I think are cut off on vps.

Could you specify what functionality of mql does not work on vps-hosting?

All MQL functionality works as in a regular terminal, including FTP/Mail/WebRequest/Push.

Launch your Expert Advisor, run it and look at the performance graphs. Don't forget to specify MetaQuotes ID in the terminal and you will receive notifications about passed limits.

Yes, I plan to make tests after I finish optimising calculations for resource intensity (I'm compressing as much as I can).

However, I have already used up the test free resources (just to familiarise myself with the service), but it's not a problem.

The question is different: if it turns out that it is too expensive to run a multicurrency Expert Advisor (it can be run on different VPS),

Is it possible to rent several VPS from one account on one login?

Lease is allocated to the bundle "trading account + trading server name", so you can make only one lease for one trading account.

I see, I think you could think over a more flexible policy, if a person wants to buy some capacity for his terminal.

ZY The service is still young, I hope it will be so in the future.

So we do not sell capacity, but hosting and latency.

If you want to buy calculated capacities, it's better to go straight to Amazon - the price tags will not just surprise you, but will hit you in the heart of your wallet.

 

How can I control the resources consumed in MetaTrader Hosting Services?

Below are several test plans:

1) The Expert Advisor runs for 50 cycles (50 timer calls after 1 minute), consumes 10 MB of RAM during each cycle and writes the same amount to a file. After 50 cycles the Expert Advisor kills itself, frees memory and erases its files.

You can see that the resources are freed instantly.


2) The Expert Advisor works 50 cycles to capture resources (RAM and the same amount in files). Each next capture is 95 per cent of the previous one. After the first 50 cycles there are another 50 cycles of resource freeing in the reverse order followed by deleting the Expert Advisor.

We can see that the memory is freed a bit less than the disc. This is due to the fact that in the Expert Advisor memory up to 1 megabyte is allocated in its own memory pool, which lives as long as the Expert Advisor is alive.


Overall conclusion: perfect resource management, visualisation and availability to the customer.
