Trailing Take-Profit / DCA Trigger

The pos_price_change_follow trigger is a dynamic exit (or entry) that activates when price reaches a threshold from the position entry, then fires when price retraces by a tolerance amount. Use it for trailing take-profits that ride momentum before exiting, or trailing DCA that buys on a bounce after a dip.

TOML Syntax

[[actions.triggers]]
type = "pos_price_change_follow"
value = "3%"            # Required: activation threshold from entry
tolerance = "-0.5%"     # Required: retrace tolerance to trigger

Parameters

How It Works

This trigger has two phases:

Phase 1: Activation

The trigger activates when the position's P&L reaches the value threshold:

• Positive value (e.g., "3%"): activates when position is up 3% from entry
• Negative value (e.g., "-10%"): activates when position is down 10% from entry

Phase 2: Retrace and Fire

Once activated, the trigger tracks the extreme price (highest for positive, lowest for negative) and fires when price retraces from that extreme by the tolerance amount:

• Negative tolerance (e.g., "-0.5%"): fires when price drops 0.5% from the tracked peak
• Positive tolerance (e.g., "1%"): fires when price rises 1% from the tracked low

Trailing Take-Profit Example

With value = "3%" and tolerance = "-0.5%":

1. Position opens at $100
2. Price rises to $103 → activation (up 3% from entry)
3. Price continues to $108 (tracked peak = $108)
4. Price drops to $107.46 → that's -0.5% from $108 → trigger fires

The trailing take-profit rode the run from $103 to $108, then exited on a small retrace. A fixed take-profit at 3% would have sold at $103 and missed the extra 5%.

Trailing DCA Example

With value = "-10%" and tolerance = "1%":

1. Position opens at $100
2. Price drops to $90 → activation (down 10% from entry)
3. Price continues dropping to $85 (tracked low = $85)
4. Price rises to $85.85 → that's +1% from $85 → trigger fires

Instead of buying at exactly -10%, the trailing DCA waited for the price to show signs of recovery (bouncing 1% from the local bottom) before adding capital.

Examples

Trailing Take-Profit: Sell on Retrace from Profit

[[actions]]
type = "sell"
amount = "100%"

[[actions.triggers]]
type = "pos_price_change_follow"
value = "3%"
tolerance = "-0.5%"

Trailing DCA: Buy on Bounce After Deep Dip

[[actions]]
type = "buy"
amount = "100%"
average_price = true

[[actions.triggers]]
type = "pos_price_change_follow"
value = "-10%"
tolerance = "1%"
