How to Solve Look-forward behaviour in SQX

I realize that whenever SQX codes (with multi timeframe) pasted in MultiCharts or Tradestation, it instantly underperform badly.

SQX uses look-forward data for higher timeframes when [0] is used.

eg. Close[0], HighD[0].

This is highly disturbing and wasting resources especially GA to continue optimizing codes in that direction.

I try to look into “What to Build“ > “# of Conditions, Period“ > “Global Lookback period Shift”

There is no “Minimum“ for Shift.

This look-forward bias generation problem could just be solved if SQX allows Higher timeframe data to specify its shift to Minimum = 1.

This is a high ROI, low effort step SQX could do in next Build.

Thanks.
