I think most of the antagonists believe you can't even trade profitably.
In this case, you could prove them wrong by showing where you went long, flat, short, flat on which bar and which price. No need to show contracts or a list of profits; just showing your trades would make the point.
Your SCT activity would show up as a series of long, flat, short, flat, long etc. trades all over the daily chart. It would blow everyone away.
If you have Tradestation this is a default setting. For financial privacy you could just do a demo run with 1 contract, or whatever.
