insufficient information
plus I would divide it up
sound business - what is the business?
and financial sense - applies to different business models and situations.
There are way more moving parts and influences in the real world plus its a single data point.
yes, if you can show that you can capture that in a sufficient win loss ratio. Only a history of actual trades will show this. Positive expectancy etc; etc;
However my 2 cents, I personally dont think the ratio is enough as there is little margin for error. Especially if human discretion is involved as this lets most folks down.
Q. What is the industry standard and most logical method used to formulate the RISK:REWARD ratio?
4.25 LIMIT SELL
3.00 LIMIT BUY ORDER
2.00 STOP ORDER
Q. Take into consideration the above market, do the applied parameters make for sound business and financial sense?
The Sharpe Ratio remains the standard, despite the criticism of its properties by some market practitioners.
No. There is nothing in there that constitutes an "edge".
