Buy on a pullback to line 2. Discovery had moved sideways for eight months in a broadening formation (lines 1 and 2) before recently breaking out of that pattern to the upside. The price has been moving steadily up over recent weeks but is now overbought, as seen by the stochastic oscillator. The price has typically corrected/pulled back after being overbought. Therefore, wait for a pullback to line 2 at the 3900c level before buying. The upside target currently being indicated is 4320c – ie, the height of the broadening formation projected up. Place your initial stop-loss as a close below line 3 (3795c). Lock in partial profits on the way up at 4150c to reduce your overall risk. Take remaining profits at/near the target.
