## Decompiler service: pricing, payment and delivery
These terms apply to MT4 / MT5 indicator and EA cracking services. Quotes are per single indicator or single EA. The final total is agreed before work begins.
### Reference prices · USD
One indicator**USD 80–200**
One EA**USD 200–500**
Indicators: USD 80–200 each. EAs: USD 200–500 each. These are reference ranges; the final quote depends on the file and agreed deliverables. Ready-made product prices do not apply to decompiler work.
### Payment methods
We accept Alipay, PayPal and USDT. USDT is supported on TRC-20 and ERC-20; agree any other network in advance. Contact us to confirm payment details, network and amount. Project payments follow your quote; the website support link is for voluntary support.
### The deposit counts toward your total
A USD 10–50 commitment deposit is required to begin cooperation, confirm the project and reserve work time, protecting both parties’ investment. It is part of the agreed total, not an additional fee.
Deposit + remaining balance = agreed total
Example: total USD 150, deposit USD 20, remaining balance USD 130.
### Refunds and cancellation
If AISTIM cannot complete the agreed cracking work and delivery, the deposit is refunded in full. If the project cannot continue for reasons attributable to the customer, including customer cancellation, the paid deposit is non-refundable.
### Delivery time
Delivery is normally within 10 hours and no later than 48 hours. Elapsed hours start once the required files and information are complete, the scope is confirmed and the deposit is received. A verification build is supplied first; source code follows customer approval and receipt of the balance. Time awaiting customer verification or payment is excluded from production time.
### Verify first, pay the balance, then receive source code
We first supply an EX4 or EX5 verification build containing AISTIM shop advertising so you can compare it with the original program. This modified build also demonstrates that we have recovered the source code and can change its content. Once you confirm it is correct and pay the remaining balance, we deliver the complete MQ4 or MQ5 source code.

## How to review your source-code delivery
01
### Check the files and scope
MQ4 is the MT4 source format; MQ5 is the MT5 source format. Check the source files and any agreed dependencies against the confirmed delivery list.
02
### Check compilation and installation
Use MetaEditor for the corresponding platform and follow the delivery instructions. Review the compiler output, then use the appropriate Indicators or Experts folder.
03
### Compare under the same conditions
Within the agreed scope, compare indicator displays and alerts or EA orders and logs using the same symbol, timeframe, inputs and test period. Start in a demo or test environment.
Acceptance follows the functions and delivery scope agreed in advance.

## Before we work together.
What is the difference between EX4 to MQ4 and EX5 to MQ5?
EX4 to MQ4 is the MT4 decompiler service for indicators and Expert Advisors, with MQ4 source-code delivery. EX5 to MQ5 is the MT5 service, with MQ5 source-code delivery. Send the file for the platform you use.
Can I enquire about an indicator or an Expert Advisor?
Yes. Both program types are covered on MT4 and MT5. When sending the file, identify whether it is an indicator or an EA and mention any companion files it uses.
Can I start with only the compiled EX4 or EX5 file?
Yes. Send the original compiled file to begin the enquiry. If available, add a preset, input screenshot or brief description of how you currently use it. These help define the delivery and acceptance scope.
Will I receive editable source code?
Source-code delivery uses MQ4 for MT4 or MQ5 for MT5. Confirm the file list in your quote, including any agreed dependencies or compiled files.
How do I confirm price and delivery time?
Send your file using any listed contact method. Price, delivery time and scope are confirmed for that file before work begins. Ready-made indicator prices in the product catalogue are separate from decompiler service quotes.
Do I need a website account or a decompiler download?
No website account or tool download is needed to request this service. Contact AISTIM by email, WeChat, QQ, phone or Telegram, and send the file in a private conversation.
What if the program uses DLLs, companion indicators or presets?
List the files and explain how they are used. Include the existing files or installation notes if available. Check which dependencies are included against the scope confirmed for your enquiry.
Does EX4 to MQ4 convert an MT4 program into MT5?
No. EX4 corresponds to MT4 and MQ4 source; EX5 corresponds to MT5 and MQ5 source. A move between platforms is a separate development or porting requirement. Mention it explicitly when enquiring.
How should I check the delivered MQ4 or MQ5 files?
Check the agreed file list and dependencies, review compilation in the matching MetaEditor, then compare displays, alerts or EA orders and logs using the same inputs and test conditions. For a discrepancy, send steps to reproduce it and the relevant error messages or screenshots.
Is pricing per file or per project?
Indicators: USD 80–200 each. EAs: USD 200–500 each. These are reference ranges; the final quote depends on the file and agreed deliverables. Ready-made product prices do not apply to decompiler work.
Which payment methods are accepted?
We accept Alipay, PayPal and USDT. USDT is supported on TRC-20 and ERC-20; agree any other network in advance. Contact us to confirm payment details, network and amount. Project payments follow your quote; the website support link is for voluntary support.
Is the deposit an extra charge?
A USD 10–50 commitment deposit is required to begin cooperation, confirm the project and reserve work time, protecting both parties’ investment. It is part of the agreed total, not an additional fee. Deposit + remaining balance = agreed total
When is the deposit refundable?
If AISTIM cannot complete the agreed cracking work and delivery, the deposit is refunded in full. If the project cannot continue for reasons attributable to the customer, including customer cancellation, the paid deposit is non-refundable.
How long does delivery take, and when does timing start?
Delivery is normally within 10 hours and no later than 48 hours. Elapsed hours start once the required files and information are complete, the scope is confirmed and the deposit is received. A verification build is supplied first; source code follows customer approval and receipt of the balance. Time awaiting customer verification or payment is excluded from production time.
How can I verify before paying the balance, and when is source delivered?
We first supply an EX4 or EX5 verification build containing AISTIM shop advertising so you can compare it with the original program. This modified build also demonstrates that we have recovered the source code and can change its content. Once you confirm it is correct and pay the remaining balance, we deliver the complete MQ4 or MQ5 source code.
Can I request restriction removal only?
Yes. Discuss time, account, combined time-and-account, WebRequest network authorization, license-key and activation-code restrictions. Delivery is usually faster and the cost lower than full source-code decompilation. The solution, quote, timing and deliverables are agreed for your file.
