S&R Power Channel Indicator: TradingView Pine Script for Support, Resistance and Buy/Sell Power

Figuring out where price might find support or resistance—and whether buyers or sellers have been in control lately—is something I run into on every chart. I've found the S&R Power Channel (Support and Resistance Power Channel) indicator useful for that. It draws a dynamic channel from the highest high and lowest low over a lookback period, offset by half of a 200-period ATR, and it shows Buy Power and Sell Power: the number of bullish versus bearish candles in that same window. That gives you both levels and momentum context in one overlay.

The S&R Power Channel doesn't repaint past bars: the upper and lower lines are derived from the lookback's high and low plus ATR, and the power counts are fixed once the bar closes. After testing it on several timeframes, I use it mainly for dynamic support and resistance and to gauge whether buying or selling pressure has dominated recently. In this guide you'll see how the indicator is built, how to add and tune it in TradingView (including via Pineify), and how to use it in real strategies with clear entry, stop-loss, and take-profit rules.

What is S&R Power Channel?

S&R Power Channel (Support and Resistance Power Channel) is an overlay indicator that plots a dynamic channel and two power metrics. The upper line acts as resistance and the lower line as support; both are based on the highest high and lowest low over a configurable length, with a band width set by half of a 200-period ATR. In addition, it shows Buy Power and Sell Power: the count of bullish candles (close > open) and bearish candles (close < open) in that same lookback. That combination gives you levels and momentum context in one view.

The logic is:

• Upper (resistance) = highest high over the length period + 0.5 × ATR(200).
• Lower (support) = lowest low over the length period − 0.5 × ATR(200).
• Buy Power = number of bullish candles (close > open) in the lookback period.
• Sell Power = number of bearish candles (close < open) in the lookback period.
• Middle line = (upper + lower) / 2, often drawn as a dotted reference.

So the channel is a rolling range of price, widened by half an ATR to allow for volatility. The power counts tell you how many of the recent bars closed bullish versus bearish—useful for confirming whether buyers or sellers have been in control. Unlike a simple Bollinger Band or moving average envelope, S&R Power combines dynamic support/resistance with explicit buy/sell pressure counts, which I've found helpful for both level-based entries and trend context.

How to Add S&R Power Channel to TradingView

TradingView doesn't include a built-in "S&R Power" or "Support and Resistance Power Channel" by name. You can add it in two ways:

Option 1 – Pineify (recommended)

1. Open Pineify and open the Pine Script editor.
2. Search for "S&R Power" or "Support and Resistance Power Channel" in the indicator library.
3. Add the indicator to your layout and adjust inputs (Length, Extend, and any line or fill colors).
4. Copy the generated Pine Script into TradingView's Pine Editor and add it to your chart.

Option 2 – TradingView Pine Editor

1. In TradingView, open the Pine Editor and paste an S&R Power Channel script (e.g. from the community or the one in this article).
2. Click "Add to chart." The indicator will overlay on the price chart.
3. Open the indicator settings (gear icon) to change Length and Extend.

Typical inputs are: Length (e.g. 130)—the number of bars used for the highest high, lowest low, and power counts—and Extend (e.g. 30)—how far the channel lines extend to the right. The whole process with Pineify usually takes about five minutes including customization.

How to Use S&R Power Channel (Practical Trading Strategies)

S&R Power Channel is best used for dynamic support/resistance and for context from Buy Power and Sell Power. Below are concrete ways to use it.

Strategy #1: Channel bounce (support/resistance)

• Setup: S&R Power Channel is on the chart; default length (e.g. 130) or your chosen value.
• Entry: Long when price touches or bounces off the lower line with Buy Power > Sell Power (or rising); short when price touches or rejects at the upper line with Sell Power > Buy Power (or rising). Optionally require a bullish/bearish close or a second confirmation.
• Stop-loss: Below the recent swing low (longs) or above the recent swing high (shorts), or just beyond the opposite channel line.
• Take-profit: The middle line, the opposite channel line, or a fixed risk multiple (e.g. 1.5–2R).

Strategy #2: Power divergence or confirmation

• Setup: Use the channel for levels and the power counts for momentum.
• Entry: When price approaches the lower line, only take longs if Buy Power is high or increasing (buyers stepping in). When price approaches the upper line, only take shorts if Sell Power is high or increasing. Use your usual entry trigger (e.g. candle pattern, RSI) in line with the power reading.
• Stop-loss: Based on your entry (e.g. below the signal bar low for longs).
• Take-profit: Next channel line or logical level.

Strategy #3: Trend filter with power

• Setup: Use the channel as dynamic S/R and the power counts to filter direction.
• Entry: Only look for longs when Buy Power > Sell Power (or Buy Power is rising); only look for shorts when Sell Power > Buy Power (or Sell Power is rising). Enter on your preferred method (e.g. pullback to the middle line, breakout of the channel).
• Stop-loss: Below/above the relevant channel line or recent swing.
• Take-profit: Trailing stop or opposite channel line.

I've found the S&R Power Channel particularly useful on 4H and daily timeframes for swing levels; on lower timeframes I use a shorter length or combine it with volume or RSI to avoid false bounces.

Best S&R Power Channel Settings

Settings should match your timeframe and style. Below are practical starting points.

Scalping (1–5 minute charts)

• Length: 30–50 (faster-moving channel).
• Extend: 10–20.
• Shorter length reacts quickly but can whipsaw in choppy markets.

Day trading (15–60 minute charts)

• Length: 65–100.
• Extend: 20–30.
• Balances responsiveness and stability.

Swing trading (4H–daily charts)

• Length: 100–130 (default 130 is common).
• Extend: 30.
• Longer length smooths the channel and aligns with swing highs/lows.

Position trading (daily/weekly)

• Length: 130 or more (e.g. 200).
• Extend: 30–50.
• Focus on major levels; fewer signals, higher commitment per trade.

In general: shorter length = more reactive channel and more signals; longer length = smoother channel and fewer, higher-timeframe levels. The ATR(200) band width is fixed in the calculation; if you need a wider or narrower band, you'd need a custom script that scales the ATR.

Advanced S&R Power Channel Techniques

Multi-timeframe analysis
Use S&R Power on a higher timeframe for major support/resistance and power context, then use the same or a shorter length on a lower timeframe for precise entry. Enter in the direction suggested by the higher-timeframe power (e.g. only longs when higher-timeframe Buy Power dominates).

Combining with other indicators

• RSI: Use RSI overbought/oversold at the channel lines to filter or confirm (e.g. only long at the lower line when RSI is oversold).
• Volume: Require above-average volume on the bounce or rejection bar for conviction.
• Trend (e.g. EMA or Supertrend): Use S&R Power for levels and trend indicator for direction—e.g. only long at the lower line when trend is up.

Risk and pitfalls

• The channel can be penetrated in strong trends; use stop-losses beyond the line or recent swings.
• No indicator works 100% of the time; always use stop-loss and position sizing.
• In ranging markets, bounces can fail; consider requiring power confirmation or a second filter.

How to Backtest S&R Power Channel

Backtesting helps you see if your S&R Power–based rules add value before risking capital. In the Pineify Editor you can build a strategy that uses S&R Power Channel in the conditions and then backtest it.

Typical strategy elements:

• Entry/exit conditions: e.g. long when price touches the lower line and Buy Power > Sell Power; short when price touches the upper line and Sell Power > Buy Power. Or use channel bounces with your own rules.
• Market orders: long/short when conditions are met.
• Take profit: middle line, opposite channel line, or fixed risk multiple.
• Stop loss: below/above the channel line or recent swing.
• Trailing stop (optional): to lock in profits when price moves in your favor.

Risk management:

• Risk 1–2% of capital per trade (position size so that stop distance equals 1–2% of account).
• Limit how many concurrent positions you have.
• Test on multiple symbols and timeframes to see where the edge holds.

No indicator works every time; backtesting shows whether your S&R Power setup has a positive expectancy and in which markets/timeframes it works best.

FAQs

What is Buy Power and Sell Power in S&R Power Channel?
Buy Power is the number of bullish candles (close > open) in the lookback period; Sell Power is the number of bearish candles (close < open). Together they show whether buyers or sellers have dominated recently and can confirm bounces or rejections at the channel lines.

What is the best length for S&R Power Channel?
130 is a common default and works well for swing and position trading. Use 65–100 for day trading and 30–50 for scalping. Longer length = smoother channel and fewer levels; shorter = more reactive and noisier.

How is the channel width determined?
The upper line is highest high + 0.5 × ATR(200); the lower line is lowest low − 0.5 × ATR(200). So the band is always half of a 200-period ATR on each side of the range. The ATR period is fixed in the standard implementation.

Can I use S&R Power Channel for crypto?
Yes. Crypto can be volatile, so the channel may be wide on short lengths. Use longer lengths (e.g. 100–130) on higher timeframes to avoid noise, and always use stops and size appropriately.

How do I avoid false bounces at the channel?
Use power confirmation (e.g. only long when Buy Power > Sell Power or rising), require a second confirmation (e.g. RSI oversold at the lower line), or trade only in the direction of a higher-timeframe trend. Avoiding very short lengths in choppy markets also helps.

Can I combine S&R Power Channel with RSI or MACD?
Yes. Use S&R Power for dynamic support/resistance and power context; use RSI or MACD for overbought/oversold or momentum confirmation. For example: only take a long at the lower line when RSI is oversold, or only short at the upper line when MACD is bearish. Keep the rule set simple so backtests stay interpretable.

S&R Power Channel works best when you use it for levels and power context and combine it with clear risk rules. Key takeaways:

• S&R Power Channel plots dynamic support (lowest low − 0.5×ATR) and resistance (highest high + 0.5×ATR) plus Buy Power and Sell Power counts.
• Add it via Pineify or TradingView Pine Editor and tune Length and Extend for your timeframe.
• Use practical strategies: channel bounces with power confirmation, power-based filter, or multi-timeframe S&R Power.
• Match length to style (shorter for scalping/day, 130 for swing/position).
• Backtest with clear entry, stop-loss, and take-profit rules and 1–2% risk per trade.
• Test on a demo or small size before going live.
