So you are using a break of the upper and lower bands in the 24-hours chart as an indication of overbought and oversold conditions respectively, right?
We have this strategy whose goal is to accumulate bitcoin, going short when price starts decreasing and reburying when price stabilizes.
The main trading idea behind the strategy is to identify short-term reversals as well as continuations and deepening of trends marked by a break down of the Bollinger Bands (BB) in the 1-hour chart, using the Percentage Bandwidth (%B) indicator, the Bollinger Bands Moving Average (BB MA) and the Bollinger Band deviation to assess momentum and volatility, optimize the take position event, and filter out late entries.
In order for a break down at the 1-hour chart to signal a reversal, several other conditions must be met:
1. The market is not in oversold territory. To check for oversold conditions, we use the Percentage Bandwidth (%B) indicator. We consider the market is oversold when %B is below 30 at the 8-hours chart and all time periods below 8-hours, up to 2 hours. What we want is that at least one of the time periods between 2 and 8 hours is not oversold.
2. There is downward momentum in the 2-hours chart. If the BB MA at the 2-hours chart is going down, then it's the first indication that the break down may have some momentum to back a short-term reversal.
There's a few other conditions we verify before taking a position, but that's the main idea...
