Try putting the code for the Indicator in the strategy (and so not calling the Indicator).

Let us know how you get on.

The issue lies in these two lines:

c5 = (indicator7 > indicator8[120])
c6 = (indicator9 > indicator10[98])

because ProOrder has to multiply 240 periods (Ema) by 120 or 98.

Since an EMA requires roughly twice its periods (in this case about 450 periods) for its calculations, the two multiplications return results well exceeding 10k.

Try reducing those two lookback values or try using an IF…ENDIF to make sure trading starts AFTER 55K bars (maybe a bit less, it’s just a matter of trying different values):

DEFPARAM Preloadbars = 10000
// Definition of code parameters
DEFPARAM CumulateOrders = False // Cumulating positions deactivated
// The system will cancel all pending orders and close all positions at 0:00. No new ones will be allowed until after the "FLATBEFORE" time.
DEFPARAM FLATBEFORE = 010000
// Cancel all pending orders and close all positions at the "FLATAFTER" time
DEFPARAM FLATAFTER = 213000

// Prevents the system from placing new orders to enter the market or increase position size after the specified time
IF BarIndex > 55000 THEN
noEntryAfterTime = 210000
timeEnterAfter = time < noEntryAfterTime

// Prevents the system from placing new orders on specified days of the week

The main issue is when you launch it in autotrading… it’ll wait quite many days before the trading starts!
