Have worked quite a lot on Amibroker platform and can easily handle this job with quality. I will develop the system in C language for the maximum speed with minimum CPU usages. This will ensure that you can run the server APP in a computer with just moderate system configuration and being developed in C, it will run at fastest speed. In trading domain, speed is prime concern so the whole system works with minimum latency. development time would be 15 days plus the time for testing and system implementation. It will be standalone kind of application so there will be no problems whatsoever in installing the system. In amibroker it will act as custom data source which will connect directly to this server app. lets discuss and get it done. You may feel price is on the higher side, but coding part will be little tricky when its being developed in C. Thanks
