Every aspect of Order Flow Ticks (Aggregated version) was carefully designed with performance in mind, so it can run even in lower-end machines.

Still, here some "Tips and Tricks" for better usage:

• Tick data are stored in RAM, even though cTrader already have good memory management:
• • Load just what's really needed for live trading.
• Params Panel already shows which parameters are supported by each mode.
• Segments Interval may change the filters analysis, use Daily interval for Intraday momentum.
• At Higher Timeframes (Price-Based Charts included)
• • Set ODF + VP to Weekly
  • Nº days / Reset Daily? parameters is now Week/Weekly.
  • All filters will be reset every Week instead of each Day.
• "Lower Timeframe" with "Small Row Size":
• • Custom MAs are made to speed up the recalculate when switching settings at Params Panel.
  • If you want to stick with cTrader Moving Averages, set [ODF] Use Custom MAs? to False
  • • Have patience if any Filter [Results / Spike / Bubbles] is activated.
• If High-Performance is needed:
• • Disable Volume Profile and/or use Mini-VPs instead. (default)
  • Use "Concurrent" on "[VP] Update Strategy" at "Specific Settings", there's a RAM usage cost, though. (default)
  • Use "Redraw_Fastest" on "Performance Drawing" settings (default)
  • Use Custom MAs (default)
  • Any filled and/or Text drawings are quite heavy when there are many of them.
• When back-testing, some drawings on Price-Based Charts are broken, but works fine in real-time.    
• Saved Settings are stored at "Documents/cAlgo/LocalStorage/ODFT-AGG ..."

Always prefer the cTrader's Store version, it's updated first.
