The tab mapper is a handy little tool that will render a guitar tab file with graphic chord diagrams displayed alongside. This comes in handy for people who just don't have every single chord shape memorized. Just plug in the web site address of a valid .tab or .crd file and hit "Go". In general, the tab mapper does a better job with printer friendly URLs. If there is more than one way to play a chord, the tab mapper will choose the most common shape. To see other fingerings, click on the chord diagram and you will be taken to the chord calculator.

Professional online decompiler
supporting any MT4 builds
The EX4 and the MQ4 files are associated with the MetaTrader 4 trading platform. They both are vital in the online trading at FOREX market. These files can contain program code of expert advisors (EA), indicators or scripts. The difference between them lies in the fact that the files of the first type are executable (*.EX4) and *.MQ4 files contain a source code. Availability of source code in this case is critically important for several reasons. Here are some of them:
Some developers betweentimes forget to attach the source code to its products. In these cases requires a decompilation, i.e. files translation from .EX4 to .MQ4 format.
Until recently a decompilation has not been a big problem. It cost less than $10 and took about a minute. There are even standalone tool for decompilation called «EX4 decompiler».
Now it's different. Starting from MetaTrader 4 build 600, MQ4 files compile to native code (like DLL). As a result the EX4 decompiler unfortunately can no longer be used.
Code optimization and compression are generally used during compilation process of the new terminal builds (600 & above). Code obfuscation is also used at compile time, and this fact greatly complicates the work to be done. Nevertheless MetaTrader Market products are encrypted additionally. These obstacles make the classical methods of reengineering (such as disassembly and static code analysis) ineffective.
Therefore, in order to recover the source code completely, these days it is necessary to work directly with a memory dumps, use debugger for the terminal and overcome restrictions of execution environment virtualization.
This painstaking work requires time and strong effort. But with due perseverance, success remains the option to achieve.
Given the above, it becomes clear that it is impossible to develop a standalone decompiler. But on the other hand, it's possible to create robust service for decompilation. And that is what we successfully did.
The cost of our services is determined individually for each case. Since the decompilation process is mainly carried out manually by professionals, the final cost of the service strongly depends on the size and complexity of the code. The cost of decompilation of MetaTrader Market ? products is much higher.
Approximate prices for our decompilation services are shown below. Typically these rates are close to the lower limit value of the typical order.
* This amount reflects the fact that we are not interested to work with indicators.
But if it's really necessary, we can professionally perform every whim you wish!
