I had a discussion with an NT7 user regarding strategy performance. He was under the impression that strategy code for live trading SHOULD NOT include chart indicators or plots, that adding those to the live code would potentially disrupt performance. That those elements should only be in a backtesting version of the code.
Is this true, or was it true with NT7 and not with NT8?
If so, should then all live code not include AddChartIndicator() or Drawings?
Appreciate the feedback.
