## How to Read the Signals
### BUY Signal
A BUY signal occurs when the price moves below or near the lower band and then crosses back above it.
More reliable BUY conditions:
* The NW middle line should be sloping upward.
* The price should preferably be above the 200 EMA.
* The candle should close above the lower band.
* RSI should turn upward from the 30–45 zone.
* The signal candle should be stronger than average or supported by high volume.
### SELL Signal
A SELL signal occurs when the price rises toward or above the upper band and then moves back below it.
More reliable SELL conditions:
* The NW middle line should be sloping downward.
* The price should preferably be below the 200 EMA.
* The candle should close below the upper band.
* RSI should turn downward from the 55–70 zone.
* The sell candle should show strong rejection.
## Best Timeframes
**15 minutes:** The most balanced option for intraday trading.
**30 minutes:** Fewer signals, but generally cleaner setups.
**1 hour:** More reliable for swing trading.
**5 minutes:** Suitable for scalping, but false signals may increase.
**1–3 minutes:** Not recommended with the current settings.
For beginners, combining the **15-minute chart with a 1-hour trend confirmation** is a good approach. For example, when the 1-hour chart is in an uptrend, you can focus only on BUY signals on the 15-minute chart.
