ASX:Z1P   ZIP CO LIMITED
Did well with my short play on Z1P , gap up nicely then fail to pass $5.37. Got in at $5.34 with a stop at $5.39 with 1,500 shares. Reduce my position at 1 R by 30% then got out the rest at $5.26, quick scalp play to the downside.

I like to calculate the stocks Standard Deviation of 1 year data, hence why $5.37 is a key level.
