Let us first start off with stating what the pattern is. The Belt Hold candlestick pattern works in both trends and occurs when there is an uptrend or downtrend and a large candle in the opposite direction occur and the body is large with little to no wick on either side of the candle.
Let us begin with an upward trend example. The market fist has to be going upwards with multiple bullish candles in a row. After that occurs and the trend may be stalling, a large bearish candle has to then form not going to high above the open and closing at the lows of the day. This indicates first that the bulls were hardly in control for the day and that secondly the bears put pressure on the equity for the entire day. You also have to look at volume because if volume is high, that means there could have been a lot of bears in the market.
The same is true for a stock that is in a bearish trend and the bulls step in and take control of the market. You have to be cautious because if there is a large move on light volume, this could indicate that there may not have many bulls in the market.
