 1 day actually looks worse then appears, it's not only confirming, but negative as well.

The downtrend is unbroken and nearly 2.5 months long.

The stop I have depicted is at the red trendline.

Here's an example of a position with a $10k account @ 2% risk.

Assumed entry= $13.00

Stop= $13.60

Risk per share= $.60 (initially-it can move down to less risk in the trend channel once it moves down)
2% of portfolio (risk money=$200)

$200 (2% of $10k) / risk per share $.60=333 shares

Total purchase= $4329 which is too much risk -nearly half of the portfolio, but illustrates the lower risk profile of the trade.

In this case, to protect against gaps, with a $10k portfolio, I'd personally take on between 100-150 shares, which leaves your exposed risk (less unpredictable gaps) at $60-$90 risk on the trade, plus commission or about a half to 1 % of portfolio.
