Demigods,

I have the following code I use as a trailing stop loss:

 

Code

#ATR Stoploss input Length = 20; input ATRFactor = 3; input AverageType = AverageType.WILDERS; def HiLo = Min(high - low, 1.5 * Average(high - low, Length)); def HRef = if low <= High[1] then high - close[1] else (high - close[1]) - 0.5 * (low - high[1]); def LRef = if high >= low[1] then close[1] - low else (close[1] - low) - 0.5 * (low[1] - high); def TrueRange; TrueRange = Max(HiLo, Max(HRef, LRef)); def ATR = ATRFactor*MovingAverage(AverageType, TrueRange, Length); def trail; if (close()[1] > trail[1]) { trail = Max(trail[1], close - ATR); } else { trail = Min(trail[1], close - ATR); } plot TrailingStop = trail;

When I build a conditional sell order in the Study Order Condition screen, I set it up as the following:

 

Code

close crosses below ATRTrailingStop_UPTREND_v2()

My problem is, seemingly at random, I'll get an error message stating "rec usage is not allowed in this context". Twice now, I've built this study from scratch, testing to see if the order will pass with each change and it'll work, but then it seems as if it just decides it doesn't want to work anymore.

For example, I set the order up last night and it worked perfectly this morning. When I tied to setup my next order, I get the error message. What am I dong wrong? I'm stumped...HALP

your definition of trail references the previous value. this is called a recursive reference. according to the docs (at the very bottom here), this is not allowed in conditional orders: (add http colon slash slash) tlc.thinkorswim.com/center/howToTos/thinkManual/Trade/Order-Entry-Tools/conditionalorders.html

Is there a broker other than TOS/Ameritrade that will allow rec usage? Or were you able to find a work around? Trying to find someplace to use an ATR trailstop to close an open position automatically with a conditional/coded orders. I keep getting this recursive data not allowed message too, and I guess will need to switch to another broker that will if possible. Thanks in advance for any help
