I am curious about reasonable values for entry parameters. Repeating some items from the manual:

• Entry has a special meaning when negative. That means use entry limit rather than entry stop.
• Stop, TakeProfit, Trail, and Entry. If the value is below half the asset price, Zorro assumes that it's a distance, otherwise it's a price.
• All the parameters have special meaning when zero. That means the parameter should have no effect.

What about beyond that? For example,

• What would it mean for Stop to be negative?
• What would it mean for Trail to be negative?
• What would it mean for TrailLock to be > 100 ?
• What would it mean for TrailLock to be negative ?

I am trying to establish reasonable ranges for these parameters because I am trying to automatically optimize them (offline).

Thanks!

I have a suggestion!

These two pages have a great deal of miscellaneous remarks, many of which are repeated.
http://zorro-trader.com/manual/en/buylong.htm
http://zorro-trader.com/manual/en/stop.htm
Please combine the two pages and summarize the behavior of this complex (7-dimensional!) system with a table. This would really help me fully understand how these parameters work in combination. (Perhaps others are in the same boat?) I can get you started. Below I've tabulated the rules extracted from the remarks. I left some ??? were I am confused.

Also, there is at least one factual error. "When parameters are set to 0 or omitted in the parameter list, global trade parameters are used". That is not true of TrailSlope, which has default=100. And StopFactor is listed on the Parameters page but not on the enterLong page.

It would really help me if you cleaned it up. Please. I will be thankful.

Entry

• Units are units of the selected asset
  
• Default=0
  
• 0 means enter at market
  
• >0 means use entry stop
  
• <0 means use entry limit
  
• abs(Entry) < current/2.0 means Entry is a distance from TradePriceOpen
  
• abs(Entry) > current/2.0 means Entry is an absolute value in units of selected asset

Stop

• Units are units of the selected asset
  
• Default=0
  
• Stop=0 means no stop loss
  
• Stop<0 means ???
  
• Stop>current means skip due to wrong side
  
• abs(Stop) < current/2.0 means Stop is a distance from TradePriceOpen
  
• abs(Stop) > current/2.0 means Stop is an absolute value in units of selected asset

TakeProfit

• Units are units of the selected asset
  
• Default=0
  
• TakeProfit=0 means no profit target
  
• TakeProfit<0 means ???
  
• TakeProfit<current means skip due to wrong side
  
• abs(TakeProfit) < current/2.0 means TakeProfit is a distance from TradePriceOpen
  
• abs(TakeProfit) > current/2.0 means TakeProfit is an absolute value in units of selected asset

Trail

• Units are units of the selected asset
  
• Default=0
  
• Trail=0 or Stop=0 means no trailing
  
• Trail<0 means ???
  
• abs(Trail) < current/2.0 means Trail is a distance from TradePriceOpen
  
• abs(Trail) > current/2.0 means Trail is an absolute value in units of selected asset

TrailSlope

• Units are percent
  
• Default=100
  
• TrailSlope=0 or Trail=0 or Stop=0 means TrailSlope has no effect
  
• TrailSlope>0 means ???
  
• TrailSlope>100 means ???
  
• TrailSlope<0 means ???

TrailLock

• Units are percent
  
• Default=0
  
• TrailLock=0 or Trail=0 or Stop=0 means TrailLock has no effect
  
• TrailLock>0 means automatically place a stop loss at the given percentage of the current profit.
  
• TrailLock>100 means ???
  
• TrailLock<0 means ???

TrailStep

• Units are percent
  
• Default=0
  
• TrailStep=0 means no automatic trailing
  
• with Stop=0 TrailStep means ???
  
• with Trail=0 TrailStep means ???
  
• TrailStep>0 means Automatically raise the stop loss every bar by a percentage of the difference between current asset price and current stop loss.
  
• TrailStep>100 means ???
  
• TrailStep<0 means ???

A matrix is a good idea for a quick overview. But negative stops and trails, or percentages above 100 just do what you expect'd them to do - they move the stop in the wrong direction or not at all, or in steps above 100 percent.
