Dynamic Speed Decay Trailing Stop MT4 converts the trailing-stop logic from our VolumeImpulse EA into a visual chart indicator. It shows how a stop can arm after a profit threshold, then tighten with an exponential decay curve that reacts to how fast price is moving in your favor.

Use cases

• Study adaptive trailing exits on real chart movement.
• Use breakout or EMA-cross entries to generate example trail states.
• Compare fast-move and slow-move stop tightening behavior.
• Read the buffers from an EA for strategy research.

What it shows

• Blue long trailing-stop line.
• Red short trailing-stop line.
• Long and short signal arrows.
• Hidden state, distance, speed, and decay buffers for automation.

Main features

• Trailing activation threshold in R.
• Start distance and minimum distance in R.
• Exponential stop-distance decay.
• Speed-sensitive decay based on favorable movement in R per second.
• Breakout and EMA-cross signal modes.

Basic use

1. Add the indicator to a chart.
2. Select breakout or EMA-cross signal mode.
3. Watch the signal arrow, then follow the trailing stop after price reaches the activation R.
4. Use the stop line as an exit reference together with your own entry confirmation and risk rules.

Important inputs

• InpActivationRR : profit in R required before the trailing stop arms.
• InpTrailStartDistanceR : stop gap when trailing first activates.
• InpTrailMinDistanceR : tightest allowed trailing distance after decay.
• InpTrailSlowDecayPerR : decay speed when movement is strong.
• InpTrailFastDecayPerR : decay speed when movement stalls.
• InpTrailFastMoveRefRps : favorable move speed treated as fast.

Buffers

• Buffer 0: long trailing stop.
• Buffer 1: short trailing stop.
• Buffer 2: long signal arrow price.
• Buffer 3: short signal arrow price.
• Buffer 4: state value, 1 long, -1 short, 0 neutral.
• Buffer 5: current trailing distance in R.
• Buffer 6: current favorable move speed in R per second.
• Buffer 7: exponential decay progress.
