Hi.
You have set such price just to draw the attention, right? Because rare indicator would cost that much. But who knows, maybe you are planning to make really complex one :)
Anyway, if you know exactly what you want to have as a result, then there would be no problems. But if you just want indicator that gives good signals and you have no idea about the logic behind but you still want them, then please ignore my bid :)
And some things may be just impossible to make. For example, some indicators are cheating, so making something really useful from them is impossible. Have you noticed that forward test (leaving it running for some time or using visual backtest chart) of the attached indicator differs much from what it shows in history when you just add it to a chart? It already means that not all signals it's giving can be trusted.
Good Luck
