Hi, i’ve tried to sort this out myself based on setting up different trailing, so this is what i am doping (not sure if works?).
My reasoning is it takes TradePrice[1] to be the last trade price, if open or closed, so if a 2nd trade was opened then the first trade is TradePrice[2] if no closes occurred. But if say 1 position close did occur, then the open price of the first trade is then TradePrice[3] etc… thats why i have put in place the flags that keep track and reset when condition isnt so to null/stop one trailing and start the next.
Note i only ever open up to 2nd accumulative, and don’t reopen any until the entire position is closed. As such for the last (aka after one trade was closed, and thus one only open) then i can use positionprice as it would be taking the price of the remaining trade and thus trailing would be correctly following that still. Also if you want to say reopen a 2nd, etc.. after it was closed, then you could reset the flags after a position closed, aka if back to 1 then flag reset, then trailing restarts to the first (use positionprice), and then when 2nd trade reopened then that would be the last TradePrice[1] again.
If you want to do 3 or 4 or more accumulative, then you just keep repeating with more flags and more settings on more positions following the same approach (many lines and time consuming though).
This is my reasoning, i am using this myself, ? unsure if as such it is working as suggested, but it does close positions and often has 2 stop-lose orders in place on my IG account when i look which appear to match my conditions. I also do use this same reasoning with “Breakevens”, and i also do see them correctly placed at positions with each subsequent trade when i check my account. I have had some issues in past where it appeared my phone was notifying me non stop of changes to the stop-lose orders: as appeared close one bar it read one and then read the other, some bug loop occurring, but i think i have sorted those out after i added in the CountOfPositions and Flags ?
Let me know thoughts ?
