This was taken on a smaller time Frame that means you are scalping. You must have added some indicators to guide your process. At this point it should probably be hitting the lower Bollinger band and signal a buy. Just s guess because I only use small time Frame after analysis using big time frame and then check for entry point on small time frame.
Don't always rely on Bollinger band to show a signal for buy or sell especially a small time frame as scalpers use. At such candle indicating bear, you also need to study other indicators , not only because the candle has gone towards the low of Bollinger band. A longer time frame is better than a short time.
When it comes to possible position neither buy or sell then I wont really just rely with BB's but also with some mix of EMA(Exponential Moving Average) and trying to look
for some bias between timeframes which do significantly talks neither on 6 hours or 15 minutes.Trying out some comparison then I would go to look for longer time frame.
Finding out possible support and resistance and trying to look those candle sticks indicators plus those averages.Basing off on the image then I would definitely
wait up until it hits a certain level on Fibonnaci before making some buys. Always remember: that crypto market can fuck up technical indicators from time to time
so its better not to fully depend on it.
