RC2_EXIT_UNIT

תוכן זה אינו זמין עדיין בשפה שלך.

Each number on an exit rule takes exactly one unit: a bare positional value (percent), or percent=, points=, price=. break_even has no price=; trailing_stop names its two numbers instead.

What it means

On an exit rule, the keyword is the unit — the way timedelta(days=…) works. percent= (or a bare positional) is a percentage from entry, points= is a distance in price units from entry, price= is an absolute level that ignores the entry price entirely. One threshold, one unit; the transpiler refuses a stale spelling, a second unit, or a unit that doesn’t exist for the rule you called.

Two rules differ:

  • self.break_even() is measured from the entry, so it takes a percent or points=, and price= is refused.
  • self.trailing_stop() has two numbers, and each one names its own unit: activate_percent= or activate_points=, then trail_percent= or trail_points=. A bare points= or price= doesn’t say which of the two numbers it means, so it is refused. Giving the same number two units (trail_percent= and trail_points=) is refused too.

Why it happens

An abbreviation or an older spelling — pct=, pts=, unit=, dollars= are all called out by name so the message can teach the right one:

class StaleKeyword(Strategy):
    trade = Symbol()
    sizing = FixedCapital()


    def execute(self):
        self.stop_loss(pct=2.0)
        if self.trade.is_flat:
            self.buy(self.trade)

Two units in one call — usually a bare positional left behind when a keyword was added:

class TwoUnits(Strategy):
    trade = Symbol()
    sizing = FixedCapital()


    def execute(self):
        self.stop_loss(2.0, points=5)
        if self.trade.is_flat:
            self.buy(self.trade)

And a points-based trail spelled with the threshold keyword, which doesn’t say whether 5 points is the activation or the distance:

class PointsTrail(Strategy):
    trade = Symbol()
    sizing = FixedCapital()


    def execute(self):
        self.trailing_stop(points=5)
        if self.trade.is_flat:
            self.buy(self.trade)

A break-even at a fixed price. Break-even is always the entry price, and its number is how far up the trade must be first:

class PriceBreakEven(Strategy):
    trade = Symbol()
    sizing = FixedCapital()


    def execute(self):
        self.break_even(price=450.0)
        if self.trade.is_flat:
            self.buy(self.trade)

How to fix it

Pick the unit that matches what you actually mean, and give it once.

class Units(Strategy):
    trade = Symbol()
    sizing = FixedCapital()


    def execute(self):
        self.stop_loss(points=5)         # 5 price points below entry (long)
        self.take_profit(price=450.0)    # absolute level, entry-independent
        self.break_even(points=20)       # once up 20 points, a stop at entry
        self.trailing_stop(activate_points=20, trail_points=10)  # from +20 points, trail 10 points
        if self.trade.is_flat:
            self.buy(self.trade)

A bare positional is always percent, so self.stop_loss(2.0) and self.stop_loss(percent=2.0) are the same rule. Dollar-denominated thresholds are not a unit yet — express them as points or as a price level.
