SSL Channel¶
Indicators · Trend
SSL Channel — high/low MA channel whose lines swap on the trend flip.
The SSL Channel (Semaphore Signal Level) is a clean, beginner-friendly trend tool that turns two moving averages into a single colour-flipping line. It tracks moving averages of the highs and the lows, and switches which one it follows based on where price closes. The effect is a line that sits below price in uptrends and above it in downtrends, flipping decisively when the trend changes — easy to read at a glance and simple to trade.
How it works¶
The block computes a moving average of the highs and a moving average of the lows over the MA period (default 10). It then tracks the close: when price closes above the high-MA, the channel locks into "up" mode and the SSL Up line follows the relevant average; when price closes below the low-MA, it flips to "down" mode. The two outputs (SSL Up / SSL Down) swap roles on the flip, and the block fires Bull ↑ when direction turns up and Bear ↓ when it turns down. The lines plot on the price pane.
When to use it¶
Use the SSL Channel as a straightforward trend filter and entry signal. The flip from down-mode to up-mode is a trend-change long signal (and vice-versa); while in up-mode, the line acts as dynamic support and a trailing reference. It's clearer and less twitchy than a raw moving-average cross because it needs a close beyond the band to flip, which filters minor noise. Like every trend tool it chops in ranges, where price oscillates across the bands — pair it with a regime filter for serious use.
Example¶
A simple trend system: wire bars into the SSL Channel and route Bull ↑ into a Tester, gated by ADX / DMI to skip ranges. Use the SSL Up line as your trailing stop via a Tester and backtest in the Tester.
Tips & gotchas¶
- Needs a close beyond the band to flip — that's what makes it steadier than a plain MA cross.
- The active line is dynamic support/resistance and a ready trailing reference.
- Chops in ranges — filter the regime (ADX / DMI, Choppiness).
- MA period tunes responsiveness — shorter flips sooner and noisier, longer is steadier and later.
