script for filtering exchanges

[SkiMaskTrader]

hello, when i run the scanner, i need to filter different exchanges IE OTC, NYSE, CBOE, AMEX. Is this possible? I couldn't find a preloaded script for this.

You don't need a script for that. Use the built-in filter option.

I'm trying to remember back when i had this question. my apologies. i was wanting to use marketwatch, which i usually do instead of scanning. Just as i can marketwatch NYSE by itself. Id like to marketwatch OTCMarkets, not just the ones that are in my WL. I did find OTC markets under the scan section for "scan in". Am i missing something or can i not see OTCmarkets in "marketwatch"?

No — You are not missing anything. ThinkOrSwim does not offer an “OTC Markets” universe inside the MarketWatch → Quotes tab.

MarketWatch can only display:
Pre‑made TOS lists (NYSE, NASDAQ, S&P lists, etc.) publicly curated lists.

But OTC Markets is not one of the selectable MarketWatch universes.
The only place where TOS exposes “OTC Markets” as a selectable universe is:

Scan → Scan In → OTC Markets​

Why this happens
ThinkOrSwim’s MarketWatch tab is built around static lists that TOS maintains.
OTC Markets, however:

Has thousands of symbols, many of which are illiquid or restricted​

Includes securities Schwab may not allow trading​

Has inconsistent data availability​

Updates frequently, making it harder for TOS to maintain as a “live” list​

So TOS exposes OTC as a scan universe, not a MarketWatch browseable list.
