Big time rookie mistake.
Bought 350 shares at $41.71 on 3JAN18. Price was falling.
Same day bought 500 shares at $39.93 in order to dilute my buying price.
I began studying the chart and saw my mistake.
On 5JAN18 I sold my shares using a trailing stop of 10 cents.
It executed at $40.41.
I had chosen the worst entry point possible.
Price was above the upper .
Oscillator had crossed indicating downward momentum.
HCM has an overall positive direction.
I'll be watching for a better entry point.
Maybe when the price is near the lower .
