TNY is trading in a Triple Bottom pattern which also appears like a descending triangle at times.
There should be an existing downtrend in place before the pattern occurs.
The three lows should be roughly equal in price and spaced out from each other. While the price doesn't have to be exactly equal, it should be reasonably close to the same price, such that a trendline is horizontal.
The volume should drop throughout the pattern in a sign that bears are losing strength, while bullish volume should increase as the price breaks through the final resistance.
The triple bottom is similar to the double bottom chart pattern and may also look like ascending or descending triangles. Traders always look for confirmation of a triple bottom using other technical indicators or chart patterns. For example, traders might note that the stock has an oversold relative strength index (RSI) before a double bottom forms and/or look for a breakout to confirm that it's a triple bottom rather than a descending triangle or other bearish pattern.
