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
The free script Dealer Gamma Levels (paste-in) takes under a minute to add. Add it to your account from its TradingView page and it stays there, ready on any chart:
Add it from TradingView › Open the published script and click Add to favorites, then add it from Indicators → Favorites.
Have an older copy of the indicator on a chart? It cannot read today's compact levels: it reports tokens ignored and draws nothing. Remove it and add the current script from its TradingView page again.

That is the whole interface. The first fields are the header — which instrument, which session, and when the board was computed — and the rest is the board itself, written compactly.
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. It also says "this script is older than these levels — update it" when the board uses names your copy of the script does not know yet, rather than drawing them under the wrong ones.
Copy without an account and you get the free set — the prior-day high and low, plus the gamma trio on symbols whose free board carries one, in the same format. A member account copies the full board. Same button, same indicator, same grammar — and the full board is the case the compact format exists for: it is the one that did not fit before.
