How to sell same contract size when calculated from account equity

  Hi

   

  I was wondering if i could get some help

   

  i use variable position sizes based on the amount of money i have in my account.

   

  the thing is i have noticed that when i look to sell this amount, it changes, mostly because of the change in price when its calculated.

  startingcapital = 100 cp=strategyprofit contractsize=(startingcapital+cp)/high if buyingcondition then buy contractsize on market end if if sellingcondition then sell contractsize on market endif

  1 2 3 4 5 6 7 8 9 10 11 12

  startingcapital = 100 cp=strategyprofit   contractsize=(startingcapital+cp)/high   if buyingcondition then buy contractsize on market end if   if sellingcondition then sell contractsize on market endif

   

  This means i always have a little bit of left over in the market and I recently noticed, it affects the efficiency of my systems.

   

  is there anyway i can create an array which remembers the value of the contract size use in a trade.

   

  this is especially helpful when there are cumulative orders on the way.

   

  i wanted to try some loops with trade price then realised that trade price could also consider sells, which is not what i want, i want to arrays to purely pick up the number of contracts of each previous trade.

   

  If  the system will always close out the oldest code, then this shouldn’t be an issue to work out.

   

  any help would be greatly appreciated.

  novembrepleut – Welcome to the forums. Please re-read the forum rules before posting again. Your topic has been moved to the correct place for strategy related questions.

  The following will just close everything that you have open:

  startingcapital = 100 cp=strategyprofit contractsize=(startingcapital+cp)/high if buyingcondition then buy contractsize at market end if if sellingcondition then sell at market endif

  1 2 3 4 5 6 7 8 9 10 11 12

  startingcapital = 100 cp=strategyprofit   contractsize=(startingcapital+cp)/high   if buyingcondition then buy contractsize at market end if   if sellingcondition then sell at market endif

  If you want to store position sizes in an array then simply do this:

  startingcapital = 100 cp=strategyprofit contractsize=(startingcapital+cp)/high if buyingcondition then buy contractsize at market a = a + 1 $myposition[a] = contractsize endif

  1 2 3 4 5 6 7 8 9 10

  startingcapital = 100 cp=strategyprofit   contractsize=(startingcapital+cp)/high   if buyingcondition then buy contractsize at market a = a + 1 $myposition[a] = contractsize endif

  ‘a’ will always be the latest position opened and ‘a’ minus 1 the previous and ‘a’ minus 2 the one before that and so on.
