Stochastic EA

New comment
 

Dear Fellow traders & advisors

I am relitively new to the trading environment and would like some advise on something.

I played around with the Expert advisors provided in MetaEditor. The ones for MA & MACD seems "fine". I managed to load that onto the chart and run some tests with it using the "Tester" facitity.

My problem is that i cannot seems to get the EA loaded onto the chart for the Stochastic example provided in MetaEditor. How do i go about loading that onto a chart? Do i need to amend something in the coding (big non no as i know nothing about programming)?

I have posted the info/coding below as it appears in the MetaEditor system.

Thanx for your advise!

Regards
