Hello,

When setting up automatic trading the Position Size has a minimum of 1, it will not take less.

On the IG platform many of the markets have minimum position sizes of less then 1, example is Crude Oil which is £0.25 or EUR/JPY which is £0.50

Is there anyway to hard code a position size into your system so you can place trades at the IG minimums ?

Thanks in advance for any help

Do you mean like below?

Try it on the DJI … it should work as it works on mine (0.2 should work also).
```
If CondA Then
Buy 0.5 Contracts at Market
Endif
```

I’ve found that the DJI is the only index that will accept position < 1 for auto trading. On the Nasdaq .5 gets rejected.

Although I have only tried this using my IG demo account with PRT I have it working with five major Forex pairs, US Tech 100 (NASDAQ), FTSE 100, and Crude Oil with 0.5 as the size coded into the system. You still use a Position Size of 1 when preparing the system to trade but that get’s overidden.

I will be using this with a live account as soon as my system is ready so I will then be able to confirm if it works correctly then.

Sorry, “overidden” was the wrong terminology. I enter Max Position Size as 1 when I set the system for auto-trading (Screen Shot 1)

And my system code has :

// Conditions to enter long positions
IF NOT LongOnMarket AND c3 AND c5 AND c7 AND TradeTime = 1THEN
BUY 0.5 CONTRACTS AT MARKET
ENDIF

This works fine

Yeah it is MAX position size … so if you set at 1 and tried to trade 2 then it would not let you.

I can’t recall testing it …
1. does it stop the System if set at 1 and code states 2
OR

2. does it limit to 1 even though code states 2 ??

Ill try later and report back.

Max position size is exactly what it says. It is the maximum position size that you let your strategy have open. It is simply a safety feature to ensure that your strategy doesn’t open masses of positions and empty your account.

To elaborate on above .. which didn’t read what I meant to say …

Does Max size = 1 allow System to continue running but limited to position size = 1 … even if code states position size = 2

(or is the System stopped??)

Ha … it’s taken me longer to type it than if I checked it out for real!? 🙂
