S&R Pro

Platform: NinjaTrader 8 (NinjaScript) - Type: indicator (overlay). This tool maps structure and liquidity - it does not produce entry signals.

Understanding ZynAlgo S&R Pro

ZynAlgo S&R Pro is a market-structure overlay for NinjaTrader 8. Instead of trying to tell you when to buy or sell, it does one job well: it marks the swing highs and swing lows that price has actually confirmed, and it draws a liquidity line at each of them so you always know where the nearest pool of resting orders sits.

Everything on the chart comes from a small, transparent set of calculations:

• Pivot highs and pivot lows over a symmetric left/right bar window (default 20 bars each side).
• The high of a confirmed pivot bar becomes the last swing high; the low of a confirmed pivot bar becomes the last swing low.
• A liquidity line drawn at each confirmed swing, starting at the real pivot bar and extending to the right.
• Four alert conditions: a new swing high, a new swing low, and price reaching either liquidity side.
• An optional candle colouring layer based on the current close versus the previous close.

Put together, you get a clean, objective map of where liquidity is parked above and below price on NinjaTrader 8, without the indicator making the trading decision for you.

Liquidity pools explained

Price rarely travels to a random destination. It travels toward areas where orders are resting. Above a swing high sit the protective stops of sellers and the breakout orders of buyers, which is why that area is called buy-side liquidity. Below a swing low sit the stops of buyers and the breakout orders of sellers, which is sell-side liquidity. ZynAlgo S&R Pro draws those two areas for you and keeps them updated as structure evolves.

• Buy-side liquidity is plotted at the most recent confirmed swing high - red by default.
• Sell-side liquidity is plotted at the most recent confirmed swing low - blue by default.
• Each line begins at the actual pivot bar and extends right to the current bar, so the level stays visible while it matters.
• A line stops only when a new swing of the same type is confirmed - it does not stop because price touched it.
• The newest line of each colour is the level currently in play; older lines remain as a record of past structure.

A common mistake - Many traders see price break a swing high and treat it as a confirmed breakout, so they chase it. Very often that move is simply a raid on the liquidity sitting above the high: the orders get collected and price returns. The second frequent mistake is expecting the swing marker to appear on the exact candle that made the high. It cannot - a pivot needs bars on both sides before it can be confirmed, so the marker always arrives later and is drawn back onto the correct bar.

How a liquidity level is defined

Nothing here is estimated or weighted. A level exists only when the pivot condition is fully met on closed bars, and the level is the exact price of that pivot bar.

• Pivot high / pivot low detection - finds a bar whose high (or low) is the most extreme within the window on both sides.
• Left bar & Right bar (default 20) - the pivot depth. Lower values confirm swings faster but produce more noise; higher values keep only more significant swings but confirm later.
• Confirmed-bar processing - pivots are only evaluated once a bar has closed, so a level never appears from an unfinished candle.
• Last swing high = the high of the pivot bar; last swing low = the low of the pivot bar. That exact price becomes the liquidity line.
• Circle markers - plotted with a negative offset so they land on the true pivot bar, above it for a swing high and below it for a swing low.
• Line width, line style and the two colours - display controls only; they change nothing in the logic.

Reading the signals

ZynAlgo S&R Pro does not generate BUY or SELL entries, and it draws no arrows, targets or stops. What it gives you is a live answer to two questions: where is the nearest liquidity, and has price reached it? Reading it works like this.

• Find the two active lines - the most recent buy-side line above price and the most recent sell-side line below it. Those are the two nearest liquidity targets.
• The alerts 'Swing High Created' and 'Swing Low Created' tell you a new reference level now exists. Remember they arrive with the pivot delay set by Left bar & Right bar.
• The alert 'Price reached buy side liquidity' fires when the bar's high crosses above the last swing high.
• The alert 'Price reached sell side liquidity' fires when the bar's low crosses below the last swing low.
• A raid alert is an attention signal, not a reversal call - the indicator makes no directional conclusion, so your own confirmation and risk plan decide the trade.

Once a level has been reached, the chart still tells you a lot about what happened there:

• Whether price closed beyond the level or only wicked through it and closed back inside.
• Whether an opposite swing forms shortly after the raid, which is how structure shifts become visible.
• The candle colouring layer, which shades each bar by close versus previous close for a quick read of short-term follow-through.
• The raided line continuing to extend to the right, a reminder that the level is still on the chart until the next same-type swing is confirmed.

Best suited for

• Traders who work with market structure, liquidity and smart-money concepts and want those levels drawn objectively instead of by hand.
• Discretionary traders who prefer a clean overlay that frames the chart and leaves the entry decision to them.
• Any market and timeframe available on NinjaTrader 8 - tune the pivot depth so the swings match the timeframe you trade.
• Traders who rely on alerts rather than watching the screen, thanks to the four built-in alert conditions.

Knowing where liquidity is resting is usually worth more than reacting to every break of a high or a low. S&R Pro is built around that idea: fewer things on the chart, but the ones that are there mean something.
