Hi,
most Forex programmers are way cheaper than employed computer scientists holding an university degree.
But please consider if they do this work for living it also cost some money.
For a programmer it does not make sense, doing a programming job 1 week for € 500 while living at expensive places such as big cities in UK, Germany or Switzerland.
But once you spend some more money, the developer is happy, works for your project only and you should get a great product.
Even a simple indicator project could take a day at least.
I don't know people who would do this for free.
When you find somebody, please let me know. I have lots of work for her or him.
Kind regards
Bernhard
