Chart1.
A simple trend line, nothing more. The second test is where things get a little interesting.
1. After the bar which im pretending was todays bar, we saw two down days of bearish movement...would I short here?...yes, sure..why not? Id be risking about 10 cents to make 30 cents (if i covered at 30.60) but to be honest, those down days were small and probably would not have caught my attention.
fast foreward about 6 days to the doji...
2. Price slightly penetrated the TL, but soon got weak. One signal to show this weakness was the "Gravestone Doji"
http://www.fxwords.com/b/bearish-gravestone-doji-candlestick.html ..and yes, just as it sounds, going long off this bar or anything near it, will probably put you down for the count. The fact that bulls lost that battle, and price closed near its lows, is something to pay attention to.
3. Another 6 days after the doji, we have this "wide range bar" on heavy volume showing up that this TL is for real, and there are sellers up here. I probably would have shorted near the close of this bar.
why the close? -- because all too often price can rally and close near its highs, or even make new highs closing as a green bar. This is common near the last 30 to 60 mins of trading..so to take out that risk, I like to buy near the close. Not always but sometimes at least.
next up: Stops, targets, etc..
