A TradingView script cannot fetch external data — so the levels travel as one line of text. Add the free indicator once, then click Copy here and paste. About ten seconds a session.
Paste-in indicator
#SYM=NQ;#DATE=2026-09-15;#ASOF=15:50Z;CR:Call Resistance=30000;HVL:HVL=29351.08;PS:Put Support=28000
That is the whole interface. The first three tokens are the header — which instrument, which session, and when the board was computed.
A pasted string does not expire on its own. Yesterday's walls on today's chart look exactly like today's walls — there is no visual difference, and the chart is wrong in the most confident possible way.
So the string carries its own date, and the indicator's info table says so out loud: the symbol, the session date, the as-of time, how many levels it drew, and a status line that reads "levels are from 2026-09-14, copy today's" when the board is older than the chart's day — or "these are NQ levels on an ES chart" when it was computed for something else. A micro counts as its parent, so an NQ board on an MNQ chart is correct and says nothing.
Copy without an account and you get the free set — the prior-day high and low plus the free gamma trio, in the same format. A member account copies the full board. Same button, same indicator, same grammar.
