Aksier....you come across as a genuine poster....Why don't you try and use a STOP LOSS on some of these trades.By doing so would have given you a positive return had you sold out of SVL at .36/.38c.
The chart shows you would have had plenty of time to get out prior to the collapse to .30/.31c.
Of course, you may have such a large parcel that, that course of action may not be viable....I don't know!
A rule I use is to not have anymore shares greater than then 10% of the average daily volume for say,the last 30 days.That way, I can generally enter and exit a stock without causing a disruption to it's price.
Just a thought.....It will improve your returns.
Although,seems to me,you are happy with your returns anyway!GOOD LUCK.
