New Strategy: BTC Signal — RSI/SMA for Altcoins

A new strategy for altcoins is live: trade any alt with RSI(14) / SMA(14) computed on BTC/USDT instead of on the alt itself. The idea: BTC is the bellwether — when the macro regime is on, trade alts; when it isn't, get out.

New Strategy: BTC Signal — RSI/SMA for Altcoins

Most altcoin strategies work like this: you take an indicator (RSI, SMA, MACD, whatever), compute it on the alt's closes, and trade off its signals. The strategy looks at the alt itself — and at whatever the alt is doing.

That works. But it has a hidden weakness: every altcoin has its own noise. Token releases, idiosyncratic pumps, liquidation events, listings, delistings. The RSI of a long-tail token swings for reasons that have nothing to do with the broader market.

Asking a different question

Our BTC-Pair Quick Insight Report shows: 92% of all actively trading Binance BTC-pairs are bear markets over 8 years. In BTC terms, alts structurally bleed. If that's the majority case, then the important question isn't "when is this alt strong?", it's "when is crypto as an asset class strong?"

And for that question there's an obvious signal source: Bitcoin itself.

The strategy

We've deployed a new strategy: BTC Signal — RSI/SMA. It works exactly like our classic RSI/SMA Cross strategy, with one difference: the signal doesn't come from the altcoin, it always comes from BTC/USDT.

Specifically:

  • RSI(14) and SMA(14) are computed permanently on the closes of BTCUSDT
  • When the RSI crosses above its SMA → buy the selected alt at the current close
  • When the RSI crosses below its SMA → sell the alt

So trades execute on the alt, but the timing comes from BTC's macro regime. When BTC starts an uptrend, you go long the alt. When BTC's trend flips, get out of the alt — regardless of whether the alt itself is pumping or dumping at that moment.

Why this is a different risk premium

Classic RSI/SMA on an alt fires ~30-80 trades over 8 years on 1W candles. Many of those are alt-specific whipsaws.

BTC's own RSI/SMA series on 1W only fires 6-12 signals per year. That's a fundamentally calmer series — because BTC has broad liquidity, lower idiosyncratic shocks, and a clearer macro regime than any individual alt.

When you transfer these 6-12 signals to an alt, you get a bot that:

  • Goes long the alt during BTC bull markets (whichever alt)
  • Sits in cash during BTC bear phases (regardless of what the alt is doing individually)
  • Has no alt-specific whipsaws
  • But also misses alt-specific bull runs that decouple from BTC (e.g. L2 cycles or meme-coin pumps during BTC sideways phases)

Where the strategy is available

Pro+ feature, live as of now at /dashboard/crypto:

  • Pick any altcoin (anything except BTCUSDT — there it would be identical to RSI/SMA Cross by definition)
  • Select "BTC Signal — RSI/SMA" as the strategy
  • All filters (200 WMA, ATR Volatility, Altcoin Season, Min Profit Guard) can be combined
  • Also works as a Live Alert and in the Signal traffic light

The Altcoin Season filter pairs especially well thematically: it adds a second regime layer focused on alt-vs-BTC strength.

What we don't know yet

This strategy is freshly deployed — we haven't run a broad bulk backtest across it yet. The theory is clean, but how it stacks up against the alt-specific RSI/SMA variant will only be visible in the data. Once we've accumulated enough user runs, a comparison report will follow.

Until then: try it yourself. On any alt of your choice, with any filter, over any timeframe. The numbers from your own backtest are more credible than any of our aggregate comparison reports.

TL;DR

  • New strategy: BTC Signal — RSI/SMA, Pro+, live as of today
  • Idea: trade alts, but use BTC's own RSI/SMA signal as the trigger
  • Background: 92% of alts bleed in BTC terms — BTC's macro regime is the more relevant filter than each alt's own indicator series
  • Available in: BacktestPage, Live Alerts, Signal traffic light, Bulk backtest
  • Limitation: BTCUSDT is blocked (would be self-reference); alts that decouple from BTC are missed

Funding Rates as a BTC Signal: We Tested It. It Doesn't Work The Way You Would Think

Backtesting Arenatradingstrategies.work

High funding rates signal overheated longs — a warning. Negative funding means shorts capitulating — a buy signal. The logic seems solid. We tested it across 6.7 years of BTC data. The results were the opposite of what we expected.

Why the same strategy crushes crypto and bombs the S&P 500

Backtesting Arenatradingstrategies.work

We ran the same RSI/SMA crossover across the top 50 coins and the top 50 US stocks — identical rules, identical window. On crypto it beats the buy-and-hold benchmark 80 % of the time; on stocks, 4 %. Why a trend-following strategy works in one market and bleeds in the other.
