I did the same changes for NonLagZigZag indicator and no yellow or orange arrows appeared

I will need to check this further because last night on GBPUSD the line moved and there were 2 valid short trades, both wins. First was sell at 2.0245 for 90 pips, second was sell at 2.0250 for 27 pips. I switch to 15 minute with pivots on chsrt for determining exit points. Entry on first trade was around camarilla H3 Short and exit at L3 Long, just below central pivot.
