Haloo~My name is Vinsley Kerk,i just a normal student at Malaysia.x a programmer of MQL4.

Halooo!! http://indo-investasi.com/images/smi...on_e_smile.gif Here is the story.I already develop a system with modified indicator,then i here that Metatrader company will introduce new client terminal which is call Metatrader 5; using mq5 as its indicator's file extension and new programming code for fast and accurate result.
So i just want to hear ur voice/comment about this.This will be in the end of this year.
My question would be:
1.Is tht any converter to convert my mq4 file into mq5 file?
2.If no,what can i do for this? http://indo-investasi.com/images/smilies/icon_cry.gif


A statement likes this:
"MT5 has a new integrated development environment called MQL5 which includes MetaEditor 5, MetaTrader 5 Strategy Tester and MetaQuotes Language 5 (MQL5). Unfortunately the MQL4 and MQL5 languages are not compatible. This means that every custom indicator and EA must be rewritten to work with Metatrader 5. It is not clear yet if there will be a tool which converts the MQL4 source code to MQL5 or allows MQL4 executables to run in MT5."

So scare to heard that..
I just a normal student ,x a programmer de.I dun know how to do
Plz give some comment on this.
Thank for reading

Not gonna happen. MT5 is starting to smell a lot like Vista! (It breaks everything that was good in the prev version) - I think a lot of us will be still using MT4 for a long time to come. Brokers will have to keep MT4 alive for years just to keep the current EA biz coming in.

IBFX and a few other brokers hung onto MT3 for years after MT4 came out (IBFX may still have it) and that was BEFORE EA's became as popular as they are today. Most people in the FX market joined during MT4 - The brokers KNOW that EA's rule the market and if you cant run EA's they'll go to brokers that will! - Notice the number of hedging/FIFO traders moving accounts overseas!! I cant imagine the stampede that'll happen if traders cant run profitable EA's.

Well MT5 will still be released in the near future, but not all MT4 brokers will be moving to MT5, while some may provide both MT4 & MT5 (ofcourse, it will cost the broker more to have both)

They aren't releasing MT5 the same time as MQL 5. It's the coding platform before the trading platform

First, you'll have to convert MQL4 code to MQL5 manually. Second, you don't have to worry about it because, in my opinion, it will take several years for MT5 to surpass MT4 in popularity among Forex traders. So, indicators/EA for MT4 will be in demand by the traders in the near future.

Well the only people with a profitable MT4 EA not wanting to convert to MT5 will be the usual crowd that resist change. The obstacle might be in finding enough skilled developers to do the work in the short term. Many more questionable EAs may not get written if programmers are otherwise occupied.

But look at the bright side - many suspect and marginal EAs will probably never get converted and MT5 will become the mark of quality and trusted code.

The problem is that the MT5 order/position system is so different from MT4 that many Forex trading systems are simply impossible to implement for MT5. Maybe that will change in the future, but currently that's a big problem for the whole industry.

This can be solved by a simple abstraction layer, a simple include file, that will solve this problem once and for all, provide the old trading API with hedging and everything, manage and track individual (virtual) trades with their magic numbers, comments, stops and targets just like it was before and simply translate the calculated net exposure from these virtual trades into a real market position, the virtual take-profits and stop-losses into real limit and stop orders, etc.

There is nothing impossible that was already possible with mt4.

Yes, such a "layer" would be nice, but it can't be created with the tools of MT5. It would be something like additional program to MT5 or a some upgraded version of MT5. When MetaQuotes was developing their new platform I don't think they wanted to leave that functionality intact (or otherwise they would have done it). So, in my opinion, it's rather pointless to expect MetaQuotes to release some solution that would work like an MT4-MT5 bridge.

Why shouldn't this be possible?

Just make an include file and in there you define all the Order*() functions and constants and give them the needed functionality. If the old names are already re-used by other MT5 functions then slightly change the names like for example the old OrderSend() will be re-implemented as OrderSend_() and so on. Then all you have to do is a search & replace in your code.

Why should this solution come from Metaquotes? Anybody here in the forum or elsewhere could write such a wrapper.

Sorry, but did you try to code some old EA with the MQL5? I did. First, I've thought that I'll be able to just substitute old fucntions and expressions with some new constructions and sets of the functions, but it turned out that it's quite impossible. With indicators that have worked, because they aren't connected with the new order/position model. But EAs now have to deal with the fact that there is only 1 (one!) position is allowed per currency pair per account. At least until the fully functional OnTrade() event handling function will be added to MQL5, it's impossible to convert 99% of the MT4 EAs to MT5 with the tools of MQL5.

I don't think automated tools are the way to do this upgrade. If in fact the upgrade is worth doing, good old fashioned ingenuity and effort will get it done. As I stated earlier, is it such a bad thing if most of the old MQL4 code is not converted? Think of the mass extinctions of the dinosaurs.

I have had second thoughts about the availibility of coders to do the work. I think my concern may be overstated if coders insist on being paid to do this kind of work. That will eliminate the frivilous requests but provide resources to those who are serious and can back up their intentions with cash. I don't think MetaTrader intended for this possibility to happen, but if it does, I don't see much downside.

Didn't you read my posting?

Thats why i suggested to write an abstraction that will emulate the old behavior, maintain it's own list of trades and orders, creates it's own ticket numbers and error numbers and everything, let the EA open as many trades as it wants, behaves exactly like mt4 to the EA, calculate the net position of its open trades list and trade only *that* at the broker.

An Example:

Open a buy 1 lot:

Abstraction will isssue "buy 1 lot" at the broker and if successful insert a *virtual trade* in it's own, self maintained list of open trades, generate a ticket number for it and return from the function.

Open a sell 1 lot:

Abstraction will issue "sell 1 lot" at the broker and insert another trade in it's list, it has now two open trades, one buy, one sell in it's list, the net position at the broker's side is zero.

Close the second trade:

Abstraction will find the second trade in it's list. to close a sell it must buy, so it will buy one lot at the broker and mark the trade as closed.

Close the first trade:

Abstraction will find the first trade in it's list, to close the buy it must sell, so it will sell 1 lot at the broker, mark the trade as closed and the net position at the broker is zero again and the two virtual trades are both closed.

Note that we violated the no hedging rule and the FIFO rule and it still worked. The abstraction will maintain it's own list of trades, its own ticket numbers, your EA trades against this virtual construct only, the abstraction itself will trade the net change in position at the broker.

Don't use MT5

You will eventually have no choice. Right now it is just in beta testing, once released you will see brokers switch to it quickly. There will be a transition period where brokers will offer both, but eventually they will shut down their mt4 servers.

The main issue I see with this idea is making sure that the code has a 'memory' of sorts.

As I have said that abstraction isn't possible to be written using the current functions of MQL5. Maybe with some external tool like DLL it can be. But not with the MQL5 alone. That's what keeping me and other coders from converting old EAs from MQL4 to MQL5.
