Hi All,

I would be very grateful for any help with this small sell side code.

The idea is for shorter time frames which I use for day trading but struggling to automate it.

Principles as below. Sell side only in this case.

1. Two longer than average bars become the new ‘range’
2. The middle of this range is the ‘mean’ for buying back.
3. Once the range is set every new bar triggers a sell unless its low crosses below the mean
4. At the ‘mean’ all shorts are bought back and the trade ends

Questions are one

1. Is this code ok as I cannot backtest it because I dont know how to (2)
2. How do I set a MAX position

   DEFPARAM CumulateOrders = True //
   
   Once Upper = 1
   Once Lower = 1
   
   c1 = abs(High[1] - Low[1]) > 1.5*averagetruerange[7]
   
   c2 = abs(High[0] - Low[0]) > 0.8*abs(High[1] - Low[1])
   
   c3 = abs(High[0] - Low[0]) < abs(High[1] - Low[1])
   
   c4 = High[1] > High[0]
   
   
   If c1 and c2 and c3 and c4 then
   Upper = High[1]
   Lower = Lowest[2](low)
   Rangebar=1
   
   Endif
   
   If Rangebar=1 and Low > (Upper+Lower)/2 then
   sellshort 0.1 lots at Upper + averagetruerange[7] limit
   
   Endif
   
   If Low crosses under (Upper+Lower)/2 then
   Rangebar=0
   Exitshort at (Upper+Lower)/2 limit
   
   endif
   
   Set stop $loss 500
   

    

Many thanks in advance
