Simple AmiBroker AFL Trading System

I am seeking a coder to create a custom trading strategy for Amibroker. Though the concept is simple, coder must have strong knowledge and experience developing with Amibroker AFL language. As well, coder must knowledge of Amibroker charts and trading strategy development. The requirements are as follows: 1) Create a trading system in Amibroker AFL formula language that is based on the zigzag indicator. A buy signal should be indicated when at the pivot low and a sell signal should be indicated by a pivot top. 2) A pivot low should be graphically indicated on the chart by a green up arrow or a green dot. Similarly, a pivot high should be graphically indicated on the chart by a red down arrow or a red dot. 3) A line should be drawn on the chart connecting all pivot highs and pivot lows sequentially. 4) The zigzag percent change should be settable with a parameter so coding changes are not necessary to adjust this adjust this parameter of the indicator. 5) The coder will provide the AFL file. 6) The coder should provide a screenshot of the fully realized Amibroker chart. There is possible additional follow up work to expand on this basic concept as a seperate project.
