(binned per thread starter's request) Help Please: EA

Hi Guys,

I have modified an old EA I found some time ago but rather than using it as it was I switched the BUY and SELL functions to work in reverse of how it was originally written. This allows it to buy/sell based upon the bias of the Stochastic rather than Buying at Oversold and vis versa.

The existing code is very simple at present.

Ideally, I would wish for it to have a Trailing Stop.

Is anyone available to add one to it for me please.

Thank You

~ David

It is Sunday Morning here and just after 7am so I still a little sleepy. I forgot to add the Code
