My dissatisfaction to the strategy tester. to the MQL developers - page 8

 
Renat Fatkhullin:

No, we believed and still believe that resources should be compressed and uncompressed as fast as possible across the entire zoo of processors. There are a lot of processors strangled by economy, including semi-vital atoms. There's a speed loss of ten times that of today's powerful processors.

Very correct approach, in my opinion. Personally, I don't see the point of compressing an executable at all. There are more important places to apply computational resources.

It is transferred to the Cloud.

Well, in my opinion, the principle of the least evil should be taken into account. Where more time is spent - on transferring extra data (compared to compressed file) or on decompressing it. In my opinion, developers are right to compress file, but use fast algorithm to do it.

 
George Merts:

Well, in my opinion, the principle of the least evil should be used here. What will take more time - to transfer unnecessary (compared to compressed file) data or to decompress it? I think that developers are right to compress a file, but they use fast algorithm for that.

Well, I gave my opinion first. I myself - always use for optimization - the lightest possible versions of experts. And I think that this is the way to do it. Therefore, in my opinion, there is no need to press them.

However, from the point of view of the developers, they have to take into account that people can stuff all sorts of stuff into EAs and that compression might be reasonable.

There is no contradiction.

Yes, if you don't shove HD movies into resources, the files are quite tiny. Compare, for example, with Android...b-r-r.

Laughing and laughing, I wouldn't be surprised if it turns out there are such originals too. Moreover, movies are packed very poorly (especially since the expert packing is done by the fastest rather than the densest algorithm).

First of all, a lot of quotes are lost for various unknownreasons, which fall either on the broker or onthe connection.

Butthat leaves 50% of the information we don't get to work. And that is my biggest dissatisfaction.

The metaquotes team has nothing to do with it. Each broker has its own quotes, the broker in turn takes quotes from liquidity providers.

Maybe you mean that the ticks in the tester are generated using older bars? Brokers (usually) have a separate server, where full quotes with ticks are stored.

Well, the fact that spread influences the expectation of trading systems is an obvious fact.
