Key Takeaways
  • The crypto market just experienced a sudden flash crash.
  • Altcoins have a more bearish chart relative to the rest of the market
  • Is the crypto market crash over, or are new lows likely this week?

Today’s sudden flash crash rattled the crypto market, undoing most of the recovery from the weekend bounce.

Altcoins are lagging behind the rest of the market and could break down in the short term.

With that in mind, let’s examine a few charts and see what lies ahead for the market in October.

Crypto Market Crash

The daily time frame shows that the crypto market cap (TOTALCAP) has fallen under a descending resistance trend line since the all-time high of $4.17 trillion on Aug. 14.

During this time, the TOTALCAP bounced at the $3.70 trillion support area (green icons), most recently on Sept. 25.

Even though TOTALCAP created a massive bearish engulfing candlestick on the day, it has since regained all of its losses, even reaching a close above that candlestick yesterday.

Nevertheless, TOTALCAP failed to break out from the 0.5 Fibonacci retracement resistance level at $3.87 trillion, which implies that the upward movement might still be corrective.

Adding to the hesitancy, the Relative Strength Index (RSI) is at 50 while the Moving Average Convergence/Divergence (MACD) is slightly below 0.

So, despite the considerable bounce since Sept. 25, today’s flash crash suggests the crypto market might still be correcting.

However, the short-term outlook points to a more bullish prediction. The bounce since Sept. 25 is an impulsive movement, evidenced by the five-wave increase (black) and the breakout from the parallel channel.

So, the ongoing crash is just wave A in the crypto market’s A-B-C correction, after which the upward trend will continue to new highs.

Why Are Altcoins Down?

While the crypto market still holds its bullish structure, altcoins paint a different picture.

The Altcoin Market Cap completed a five-wave decline between Sept. 18 and 26.d

Unlike the rest of the crypto market, the altcoin bounce looks corrective, since it is contained inside an ascending parallel channel.

The altcoin market cap has nearly broken down from the channel, while the RSI and MACD are getting rejected by their bullish levels at 50 and 0.

If the count plays out as expected, the ALTCAP will complete wave C at a low of either $1.01 trillion or $956 billion, depending on its proportion with wave A.

Mixed Signs

Overall, the crypto market is at a critical juncture.

The short-term structure shows room for another leg higher, but altcoins look ready to break down.

Bitcoin may create a higher low, while altcoins create slightly lower lows before the upward trend resumes in October.
