True Center Band (TCB) indicator for ProRealTime

The True Center Band (TCB) is a sophisticated, non-repainting channel indicator designed to provide a clear framework for price action. Unlike traditional moving averages or regression channels that can lag or change past signals (repaint), the True Center Band (TCB) offers a reliable, dynamic map of market trends and support/resistance levels.

Here is a detailed guide on how to use the TCB indicator and why it is a vital tool for modern technical analysis.

The Anatomy of the True Center Band

The TCB indicator consists of a central anchor and multiple layers of price boundaries:

• The Center Line: This acts as the "gravitational center" of price action for a given period.³ It helps traders identify the core trend direction.

• Three Channel Bands: These bands are plotted above and below the center line, representing different tiers of support and resistance.

  • Inner Bands: Often represent "fair value" or minor retracement levels.

  • Outer Bands: Mark the extreme boundaries of price action, often indicating overbought or oversold conditions.

Why the TCB is Unique: The "Non-Repainting" Advantage

Many channel indicators, such as the Center of Gravity (COG) or standard Polynomial Regression Channels (PRC), use future data to smooth out their lines. This results in repainting, where the indicator "corrects" itself after the price moves, making backtesting look perfect but real-time trading difficult.

The True Center Band is specifically engineered to never repaint. Because it is calculated using only past and current data, the lines you see on the chart are fixed once the bar closes. This reliability is crucial for:

• Backtesting: You can accurately see where signals would have occurred.

• Real-Time Execution: You can trust that a touch of a band won't disappear five minutes later.

How to Use TCB for Technical Analysis

1. Trend Identification

The slope of the Center Line provides an immediate visual of the trend.

• Bullish Trend: A rising center line with price staying mostly in the upper channels.

• Bearish Trend: A falling center line with price staying mostly in the lower channels.

• Sideways Market: A flat center line indicates a range-bound market where you can "fade" the outer bands (buy low, sell high).

2. Dynamic Support and Resistance

Traditional horizontal levels only account for price history. TCB provides dynamic levels that move with time and volatility.

• Entry Points: Traders often look for "buy the dip" opportunities when the price touches the lower bands during an uptrend.

• Profit Targets: The upper bands serve as natural exit points or targets for long positions.

3. Volatility Assessment

The width of the TCB channels automatically adjusts based on price range.

• Narrow Bands: Signal low volatility and a potential "squeeze" before a breakout.

• Wide Bands: Signal high volatility and a mature trend that may soon require a "mean reversion" back to the center line.

Optimization and Settings

The TCB is designed to be simple, featuring primary parameter: The Period.

• Short-Term Trading (15-20 Period): Best for scalping or day trading on minute charts.¹⁰ It reacts quickly to price shifts.

• Long-Term Analysis (50+ Period): Ideal for daily or weekly charts to identify major "Value Zones" and macro trends.¹¹

   

Conclusion

The True Center Band is more than just a visual aid; it is a mathematical framework that helps traders "frame" price action. By removing the uncertainty of repainting, it allows for a disciplined approach to wave trading, trend following, and mean reversion.

We use the same algorithm for the TCB on all platforms, it will work exactly the same on any platform, you can also view some screenshot and videos we took from other platforms.
 

You might wonder, is there an indicator can show the trend, different levels of support and resistance, and the boundary of price action? The answer is yes, True Center Band (TCB) indicator is capable of doing all of them.

It consists of one center line to measure the center of price range within a given period,
and three channels (bands) represent different support and resistance levels.

True Center Band may look like some other indicators, such as Center of Gravity (COG) and polynomial Regression Channel (PRC). But there is one major difference, TCB never repaints, because it is not calculated by future data. Reliability makes TCB looks good, works better.

True Center Band is specially designed to work on all intraday charts (tick, mins, renko, range, etc.) and daily chart. It also works on all markets (Stocks, Futures, Forex, Options, ETF, etc.)


A good indicator should make complicated things simple.
Therefore, there is only 1 parameter.

Period: the number of bars used to calculate the True Center Band (TCB).

It's very easy to understand, if you want TCB to plot a long-term trend then set a big number such as 50.

If you want to see a short-term trend, then set a small number such as 15.

For the same symbol, same date and time range and timeframe, if we load 10 days TCB will plot like the image below. The bands become much wider than the chart above, that's because the price range in the past 10 days is wider than the past 2 days.

For Minute chart of more than 30mins, in order to see a longer range of support and resistance levels, it's better to load more days in "Chart Settings".

If we load 50 days for a 30-min chart, the support and resistance lines will be calculated by the data from the last 50 days.

If you want to see the recent range of support and resistance levels, then just load the number of days you desire.
