Hi Thanhtamlee11,
I'm a Senior developer (see my CV) and I have more than 6 years of EXP in MT4 coding.
Even if I'm newer to FreeLancer, I've participated to a lots of MT4 projects, from simple to very strong projects, with external modules, more over I have participated to ForexTester software (even if I only have the version one licence), and I've created the Mql2Mq4 software which convert automaticaly a MT3 EA, Indicators, scripts to MT4.
It is possible to create and test strategy on Forextester v2 without licence, but limited to one month, which seems enought, depending of your EA rules and strategy.
Your project seems very interesting, and I know both Forextester and MT4.
Question, I do not see the attached image ?
For all projects I propose these following steps :
1. Analyse all your EA rules and ask more details if needed
2. Implement them into an EA
3. Test the EA with all rules
4. Give you the binary version of EA to test it
5. You validate the EA, I will sent you the full source code
6. Or correct Issues, fix rules, ... according to your feedback
7. Even if the Project is closed, you will be able to contact me to fix issues WITHOUT PAYING like an After Sales Service :)
I hope we can work together.
Regards
Greg
