using oppies to gain leverage

I thought I might share the strategy I used today. I figured FDL was ready to make a move, which it did today. The problem is that I had no more capital available to top up. I was holding 680K heads. I sold 440K heads for 11.5c and bought 1,120K oppies at 4.5c (the oppies seem to trade at a constant 3 cent premium being able to be exercised at 10 cents) I now effectively control 1,360K shares. That is double the amount I had control of before for no money down. I have doubled my stake and it cost me nothing. Now I will now make $13,600 for every 1c move in the sp instead of $6,800 previously.

Come September, let's say FDL is trading at 50 cents and I wish to exercise my 10 cent oppies so I will need $112,000. I can then sell my remaining heads for $120,000 and exercise the oppies or sell any combination of heads and oppies to come up with the money to exercise the oppies or just sell the oppies at a profit.
