Stop loss ?
Is it based on any technical parameter ?
No ... i dont believe much in technical indicator...
stoploss and targets are a big subject to discuss... according to market mechanics we should change our stop/targets...
suppose in a bull market ... As an investor i dont need a stoploss at all... and target will be till the end of over all trend... Bull market can run for years...
lots of external factors can affect our trades... example global news... Global market trend... our own market news...
So its very difficult to stick a particular rule...
