Every system on this site trades a fixed reference line or range. This one uses a channel that only reacts to price itself: the highest high and lowest low of the last 20 bars, no average and no standard deviation involved. Charts below are interactive. Click Play on any setup and watch the signal bar fire, then the entry, stop, and target draw themselves, computed live from the actual candle.
“A wick past the band is not a signal. Only a trend bar that closes there counts, and until that close prints, there's nothing to trade.”Jason Parker · Founder
A handful of terms show up again and again below. Click one to see what it means.
Wait for the signal bar to close, then buy if price on the next bar trades one tick above the signal bar's high. The close confirms the signal. It isn't your entry price.
Wait for the signal bar to close, then sell if price on the next bar trades one tick below the signal bar's low. The close confirms the signal. It isn't your entry price.
The stop sits one tick past the far side of the signal bar. The target sits half that bar's range away from entry. The channel breakout bar setup below runs a $0.90 signal bar, for an entry near $185.26, a stop near $184.44, and a target near $185.71. The channel itself never enters that math directly. It only decides which setup is on the table: whether a close counts as a breakout, a ride, a fade, or a reclaim.
Play with the numbers below. The default reflects the channel breakout bar setup's own risk to reward.
≈70% is the honest break-even line once spread and slippage are priced in, not the raw number the math alone gives you. ≈80% is doing well. ≈90% is among the best scalpers running a system like this.
Four different jobs, same closing rule underneath all of them. A channel breakout bar closes past the band for the first time, past a level the last 20 bars never traded through. A band ride continuation bar closes at or beyond the band again, bar after bar, in a market that's already trending. A false break fade bar closes back inside the channel right after a wick poked past it, undoing the breakout before it started. A channel midline reclaim bar closes back through the middle of the channel after an earlier break already failed. All four still come down to the same close: near the bar's own high for a long, near its own low for a short.
One honest note before the setups. A 20-bar Donchian Channel only moves when price sets a fresh 20-bar high or low. It can sit flat through a slow, choppy stretch and then jump wide the moment a single bar spikes through it, which makes the band itself a lagging, sometimes jumpy reference, not a smooth line like a moving average. The channel narrows down which setup is on the table. It doesn't replace the signal bar's own close.
Each chart shows the setup forming, with the channel's midline and both bands plotted underneath. Hit Play and the signal bar fires, then the entry, stop, and target draw in, computed the same way you'd compute them live, straight from the signal bar's own high, low, and close.
The pattern: a trend bar closes past the channel's upper or lower band, past a level the last 20 bars never traded through.
Long: a green trend bar closes above the upper band, printing a fresh 20-bar high. Buy the close.
Short: mirror this to the downside: a red trend bar closes below the lower band, printing a fresh 20-bar low. Sell the close.
The pattern: price is already trending, and bar after bar keeps closing at or beyond the same band instead of pulling back toward the midline.
Long: a green trend bar closes at or above the upper band again, the third or later bar in a row doing that. Buy the close.
Short: mirror this to the downside: a red trend bar closes at or below the lower band again, the third or later bar in a row doing that. Sell the close.
The pattern: a wick pokes past a band, but the very next bars fail to hold there and close back inside the channel, undoing the breakout.
Short: a wick pokes above the upper band, price fails to hold above it, and a red trend bar closes back inside near its own low. Sell the close.
Long: mirror this to the downside: a wick pokes below the lower band, price fails to hold below it, and a green trend bar closes back inside near its own high. Buy the close.
The pattern: price already broke a band and failed to hold it, drifted back through the channel, and now closes back through the midline going the other way.
Long: price broke the lower band, failed to hold, and a green trend bar closes back above the channel's midline near its own high. Buy the close.
Short: mirror this to the downside: price broke the upper band, failed to hold, and a red trend bar closes back below the channel's midline near its own low. Sell the close.
A wick past the band is not a signal. Trading the poke itself, before a trend bar actually closes past it or back inside it, is how this system's edge disappears fastest.

Common questions about trading this specific system, answered straight.
It's a 4-minute PLTR system built around a 20-bar Donchian Channel: four setups (channel breakout bar, band ride continuation, false break fade, channel midline reclaim) that all share the same entry, stop, and target math once a signal bar closes. Entry is one tick past that bar's own high or low, the stop is one tick past the far side, and the target is half the bar's range away.
Bollinger Bands are a moving average plus bands set a standard deviation away, so they widen and tighten with volatility even if price never makes a new high or low. A Donchian Channel is just the highest high and lowest low of the last 20 bars, redrawn every bar, so it only moves when price actually sets a fresh extreme. Same entry, stop, and target math underneath either system, once the signal bar closes.
No. A shorter or longer lookback only changes where the channel's bands sit and how often a new one prints, not the entry, stop, and target formula, which is always computed off the signal bar's own high, low, and close. Run a different lookback if you want, the trade math underneath stays identical.
