One of the simplest and most effective filters for altcoin trading is what I call the $100K Rule.

In a market like this, things pump fast. The real danger is not getting in late, it’s being stuck in something with no liquidity when you want out. That’s where most people get hurt. Liquidity matters more than almost anything else.

Here’s the setup. It takes about 30 seconds.

Open any Binance spot pair on TradingView, for example SOL/USDT.

Click Indicators and search for “VolUSD” by niceboomer.

Add it, then set the MA length to 60.

What this shows is average traded volume in USD per candle. On the 1 minute timeframe, smoothing it over 60 periods gives you a clean, realistic view of how much real money is flowing through the pair.

The rule is simple.

Only trade coins that show at least $100,000 in average VolUSD per 1 minute candle.

If a coin passes that threshold, there’s real depth on the order book.

You can enter and exit with size without massive slippage or sitting there watching your sell order not fill.

Low volume microcaps can still 10x, sure. But most people never realize those gains because liquidity disappears the moment they want to sell.

That’s how bags are made.

Use this filter and you immediately avoid a huge percentage of bad trades.

Trade whatever narrative you like, just make sure there’s actual flow behind it.

Simple. Boring. Extremely effective.
