Hi, I’m struggling to pick up the lingo – mainly the financial stuff as I’ve got programming experience (but not been trading much). Apologies therefore for some stupid questions.

I’m looking for a very simple example that I can build on, e.g.:
1. Open 2 positions: BUY and SELL
2. If the BUY price goes up by X% compared to the opening rate, close the BUY position and then open another
3. If the SELL price goes down by X% compared to the opening rate, close the SELL position and then open another
4. If either position goes into the red by Y%, close it and then open another in the same direction

I only want one open position in each direction at any given time to limit exposure.

I tried the below but it didn’t seem to work (opened too many positions?):

Defparam cumulateorders = false

n = 50 // Number of shares
x = 10 // Profit
y = 20 // Max loss

// Only ever have one position open in each direction
IF NOT LONGONMARKET THEN
    buy n shares at market
ENDIF
IF NOT SHORTONMARKET THEN
    sellshort n shares at market
ENDIF

// Close at profit or loss
set target %profit x
set stop %loss y

A few questions also:
a) Is the order fee taken into account for profit or loss (the last two lines in my example)?
b) I also can’t figure out why, when I use the ProBacktest, the timescale resolution drives the number of positions that get opened? I only want two (one in each direction) at any given time. What settings should I use to simulate this?
c) Do I need to set restrictions around trading days, e.g. not to buy/sell on Saturdays or Sundays or will orders for these days just be ignored?

Many thanks in advance for any pointers! Once I get up to speed I will of course share my success (fingers crossed) 🙂
