How Long To Forward Test?

[DallasSteve]

I wrote a trading system and backtested it 4 months and it was a failure. 0% return. But I liked the concept and I started testing it in a demo account. It has made an average of about 300 pips per day (forex) over 4 days. I know it will probably crash so I'm not taking it live.

The question is: How many days (realistically) could a failing system turn a profit before it finally starts to go negative? (this is a sytem that makes about 50 trades per day)

It’s a major concern when a trading software vendor asks questions that are this dumb.

When do you think you’ll be able to start flogging us this failing system?

What are you selling? Is it patio chairs or something?? It can't be trading related if you're asking these kinds of questions.
