MQL5 Cloud Network: Are You Still Calculating?
It will soon be one year since the MQL5 Cloud Network has been launched. This leading edge event ushered in a new era of algorithmic trading - now with a couple of clicks, traders can have hundreds and thousands of computing cores at their disposal for the optimization of their trading strategies.
All issues regarding network installation, setup and structure are covered in the FAQ section on the official MQL5 Cloud Network website.
And yet there is one question that has been eating many of us up: "How
A new option has recently been added that now allows every cloud agent
customer to see how many tasks were computed over the optimization of
his Expert Advisor. All you need is to go to Agents ->Tasks in your
you will be able to see in how many passes the optimization was
completed, when it was performed and how much it cost you. The
Screenshot above suggests that the optimization of the Expert Advisor
MACD Sample available in the standard delivery for EURUSD on H1 (symbol
and time frame, respectively) began on September 20, 2012 at 14:20.
The number of passes (completed tasks) at this point is zero as the
screenshot was taken right at the start of the optimization.
The Figure below shows settings made for the parameter optimization.
the combination of the MACD Sample external parameters, the number of
passes totaled over 152 billion. Even if we assume that every pass
requires 1 second of time, the total optimization time will be 485
years. In the settings, select the interval from 2012.01.01 to
2012.08.01 and the tick generation mode "Every tick" as when testing in
the Automated Trading Championship 2012 Automatic Tests.
Slow Complete Algorithm (complete parameter search) as the optimization
mode and start the optimization. The strategy tester will independently
determine that the given number of passes requires the use of the Fast
Genetic Based Algorithm and will switch to this faster optimization
mode. The optimization employing the Fast Genetic Based Algorithm only
involves agents of one MQL5 Cloud Network task manager since it is the
responsibility of the task manager to redistribute tasks among the
Figure above shows that 2172 tasks were distributed among the agents of
the access point Europe 2 and the computing of 2168 of them has
currently been completed.
that the strategy tester switched to the Fast Genetic Based Algorithm
can be easily verified by number
10496 displayed in the line of estimated passes. The screenshot below
suggests that 2815 passes out of 10496 have been completed by now.
To monitor the optimization chart, let us switch to the corresponding tab.
the optimization, we switch to the Journal where we can see that the
optimization completed on pass 8704 and the total of 134 tasks were
computed using local agents (3% of the total number of tasks) as opposed
to 3892 tasks computed using cloud agents.
we can find out the answer to the question asked at the beginning -
how much it costs to optimize the Expert Advisor MACD Sample over the
interval from 01.01.2012 to 01.08.2012 in the "Every tick" mode. We go
to our profile and see the answer in the "Agents" tab being 0.23
Cloud agents computed 3892 tasks in 24 minutes which fully agrees with the strategy tester data.
we had almost 500 agents working for us for 24 minutes and it only cost
us 0.23 credits. If you only had 4 local agents involved, you would
have to wait (500 cloud agents * 24
minutes / 4 local agents) for 3000 minutes which makes 50 hours or a bit
days for the optimization to finish. Thus, you bought 50 hours of
computations for the trading strategy parameter optimization for 0.23
credits. And now think what you can buy for $0.23 in real world - not
much, is it?
So, we had almost 500 agents working for us for 24 minutes and it only cost us 0.23 credits. If you only had 4 local agents involved, you would have to wait (500 cloud agents * 24 minutes / 4 local agents) for 3000 minutes which makes 50 hours or a bit over 2 days for the optimization to finish. Thus, you bought 50 hours of computations for the trading strategy parameter optimization for 0.23 credits. And now think what you can buy for $0.23 in real world - not much, is it?
I think the charges are applied to the number of passes and not the time.
0.23 / 3892 = price per pass
I am not so worry about the payment but I found that the cloud was too slow. Is there a way to limit slow computation responses?
true true :)
Why I can't use Cloud Network resently ?
It's not used after double click permit use " Cloud Network"
and It's normal month ago.
Since we are in trading business, maybe you've heard the term : Supply and Demand.
Maybe it's too much supply in agents and less demand for cloud.
