In the context of seeking direction in the overall cryptocurrency market, BTC (Bitcoin) 4-hour candlestick chart has recently shown a "strong breakout" trend - comparing key time nodes, it can be seen that the current price of BTC has significantly risen from the low of 04:00 on September 20, 2025, and has notably rebounded from the oscillation platform at 12:00 on September 19, although there is still a gap compared to the high point at 00:00 on September 19, it has formed a "large bullish candlestick leading the rise + the last bullish candlestick supporting" volume-price resonance pattern. More importantly, recent trading volume has risen in sync with the price, MACD bullish momentum has continued to strengthen, combined with the clear buy and sell points and support and resistance zones provided by BOSS Wallet, the short-term upward momentum of BTC has been initially established, and whether the resistance level of 117878 USD can be broken will directly determine whether it can open up a new round of upward space.
1. Core characteristics of the 4-hour K-line: volume and price both rise, indicating strength, and the bullish line structure lays the foundation for rising.
From the details of BTC's 4-hour K-line, recent trends present three major 'strong signals', providing solid support for the short-term market:
1. Price trend: large bullish body breaks the situation, key nodes show significant repair strength
Comparing the key time points from September 19 to 20, 2025, BTC's short-term trend shows a pattern of 'rapid recovery + strong continuation':
Compared to the low point at 04:00 on September 20: a significant increase, with a single 4-hour K-line closing with a 'large bullish body', an increase of over 2%, and the closing price is nearly 2500 USD higher than the opening price. It not only broke through the '114000-115000 USD' short-term oscillation range but also formed a 'bullish engulfing' pattern, completely reversing the previous pullback trend;
Compared to the oscillation platform at 12:00 on September 19: significantly rebounding, from around 113500 USD at that time back to the current range, repairing nearly 80% of the pullback space caused by 'macroeconomic interest rate concerns', and the last 4-hour K-line closed as a bullish candle, with the closing price greater than the opening price, maintaining an entity length of over 1000 USD, indicating a solid bullish dominance;
Compared to the peak at 00:00 on September 19: although there is still a slight gap (the current price is about 1.5% lower than the high at that time), the gap is rapidly narrowing, and during the approach to the previous high point, there has been no 'stagnation' sign. Instead, trading volume has increased simultaneously, indicating ample breakthrough momentum.
It is worth noting that this rise is not an 'isolated market trend'—after BTC broke through 115,000 USD, it led mainstream currencies like ETH and SOL to rise in sync, forming a pattern of 'leading bull + sector linkage', further strengthening market bullish sentiment and laying the groundwork for subsequent breakthroughs of key resistance.
2. Volume changes: trading volume surges in sync, confirming the effectiveness of the volume-price resonance in the rise
Perfectly complementing the price trend, the BTC 4-hour cycle volume shows a 'resonant rise': the latest 4-hour trading volume increased by 58% compared to the previous two 4-hour cycles and grew by 45% compared to the average trading volume on September 19, reaching a new high for the 4-hour cycle trading volume in nearly 3 trading days, and the price and trading volume are showing a positive correlation of 'synchronous rise', without the previous common 'volume-price divergence' risk.
This volume-price resonance conveys two key pieces of information:
First, 'buying actively enters the market': the increase in trading volume comes from 'bullish funds actively laying out'—data shows that in the latest 4 hours, the buying volume in the '115000-116000 USD' range accounts for over 60%, mostly large orders of '500,000 - 1,000,000 USD', suggesting that institutions or large investors choose to 'buy on dips' after 'digesting macroeconomic negative news', providing core momentum for price increases;
Second, 'support strength is fully enhanced': although prices are rising rapidly, the support volume in the '114500-115000 USD' range has simultaneously increased by 62%, mainly composed of '200,000 - 500,000 USD' medium and large orders, forming a 'stair-step support', effectively resisting the selling pressure from short-term profit-taking, avoiding the price from 'rising and then falling', ensuring the continuation of the upward trend.
2. Technical indicators: Bullish signals continue to strengthen, oversold recovery and momentum accumulation provide support
BTC 4-hour cycle technical indicators further confirm a 'bullish momentum', creating a synergistic effect with volume and price resonance:
1. MACD indicator: Bullish momentum accelerates, bearish momentum decreases to low levels
Although the MACD is currently in a 'no obvious trend' transitional phase, the core details release clear bullish signals: the MACD histogram 'remains negative and shortens rapidly', shrinking from -1200 to -300, a reduction of over 75%, indicating that bearish momentum has diminished to a recent low, while bullish forces are accelerating accumulation. Further observation of the MACD dual lines shows that the fast line (DIF) has risen from -800 to -200, while the slow line (DEA) remains around -500, with the gap between the fast and slow lines rapidly narrowing. If the subsequent histogram turns positive and the dual lines form a golden cross, it will confirm that 'the trend shifts from oscillation to rising', opening up greater upward space for BTC.
2. KDJ indicator: oversold recovery continues, significantly reducing pullback risks
Although the KDJ indicator currently shows no clear golden or death cross, its core values convey positive signals: the KDJ value has risen from 7 to 11, while still in the 'oversold zone' (below 20), it has exited the 'severely oversold' range, and the recovery rhythm is steady, with no pressure from 'rapid overbought' corrections. Historical data indicates that when the BTC 4-hour cycle KDJ value rises from 7 to 11, the probability of prices continuing to rise within the subsequent 4-8 hours exceeds 80%, with an average increase of about 1.5%-2.5%. The core logic is that 'during the oversold recovery process, buying gradually dominates without triggering excessive speculation.'
In light of the current trend, the steady recovery of KDJ and the volume-price resonance form a complementary relationship—avoiding the 'rapid rebound and then pullback after overselling' short-term volatility, while reserving momentum for subsequent breakthroughs at the resistance level, making the upward trend more sustainable.
3. Support and resistance: 114946 USD solidifies the bottom, 117878 USD becomes the 'watershed' for the rise
BOSS Wallet provides support and resistance levels, precisely delineating the core range for short-term speculation on BTC:
Recent support level (114946 USD): a cornerstone for mid-term rises, overlapping with the dense buying area: this support level is not only BOSS Wallet's explicit 'buying point two' but also highly overlaps with the recent buying density area of '114500-115000 USD', corresponding to the MA10 (10-period moving average) position. In the past two pullbacks, it has received massive support of over 500 million USD, and if prices pull back subsequently, this range will likely become a 'bullish defense position' to avoid trend reversals.
Recent resistance level (117878 USD): short-term upward target, echoing previous highs: this resistance level is marked by BOSS Wallet as 'selling point two', and is also close to the recent high on September 19 at 00:00 (117583.56 USD), which is a combined area of 'psychological pressure at integer levels + release of previously trapped positions'. From the current momentum, if trading volume remains high, the probability of BTC breaking through this resistance level is relatively high; after the breakthrough, the next target will point to the 119000-120000 USD range, corresponding to the extension line of the previous upward trend.
3. BOSS Wallet practical strategy: Tiered layout to seize opportunities, stop loss and take profit to lock in gains
In response to BTC's current strong trend, the 'buying points, selling points, and stop-loss points' provided by BOSS Wallet are highly practical and can be executed in batches according to investors' risk preferences:
1. Buying strategy: build positions in batches relying on support levels, balancing safety and returns
BOSS Wallet provides two buying points, corresponding to the needs of 'conservative' and 'aggressive' investors, and is highly compatible with the current trend:
Buying point one (115125.12 USD): conservative layout, corresponding to a safe margin for pullback: this price is slightly above the support level (114946 USD), representing a 'reasonable entry point after a pullback', suitable for investors with lower risk tolerance. If BTC experiences a short-term pullback to this range, and signals such as 'trading volume shrinking (reducing by over 30% compared to current)' and 'MACD histogram continuing to shorten' appear, a small position can be built, with the position suggested to be controlled within 3%-5% of total assets, relying on support levels to reduce short-term volatility risks;
Buying point two (114946.0 USD): aggressive layout, corresponding to strong support level: this price completely overlaps with the support level and is the 'most concentrated buying area' recently. It is suitable for investors with higher risk tolerance and a desire for maximizing returns. If BTC pulls back to this price and does not fall below the 'long position stop loss point (114549.49 USD)', a moderate increase in position can be made, with the position suggested to be controlled within 5%-8% of total assets, relying on the support level and volume resonance to capture the returns from breaking through the resistance level.
2. Stop loss and take profit: clarify risk boundaries, realize profits in batches
Long position stop loss point (114549.49 USD): risk bottom line, exit if it breaks: this price is below the support level (114946 USD), and is the overlapping position of 'recent pullback low + MA30 moving average', which is the 'life and death line' of the short-term uptrend. If the BTC price falls below this level, it indicates the failure of previous volume-price resonance and insufficient bullish momentum, requiring strict stop-loss exit to avoid exacerbating pullback risks, with stop-loss range controlled within 0.5%-1% of the entry price, which is a 'low-risk stop-loss setting';
Selling point one (117583.56 USD) + selling point two (117878.0 USD): tiered profit-taking at resistance levels: the two selling points correspond to the 'recent high point' and the 'key resistance level', and it is recommended to perform 'tiered profit-taking': when the price first reaches 117583.56 USD (recent high point), 40% of the position can be reduced to lock in some profits; if it breaks through this level and stabilizes above 117878 USD with increased volume, 30% of the position can continue to be held, targeting 119000 USD; the remaining 30% of the position can be set with a 'trailing stop loss' (e.g., exit if it falls below 117000 USD), balancing subsequent profits and risk control.
3. Short-selling strategy: participate cautiously under current momentum, strictly control risks
Given the current strong upward trend, the 'short position stop loss point (118171.48 USD)' provided by BOSS Wallet should be used cautiously: only when BTC shows signals such as 'volume surge stagnation (price not rising but trading volume surging)' and 'MACD histogram starting to grow longer' at the resistance level of 117878 USD, can one attempt a small short position, with the position controlled within 1% of total assets, and strict stop loss set above 118171.48 USD to avoid significant losses due to countering the main trend. For ordinary investors, the current stage of 'long positions as the main strategy, short positions as a secondary strategy' is a more prudent choice.
4. Risk warnings and responses: pay attention to macro and resistance level reactions, avoid blind chasing of highs
Although BTC's short-term trend is strong, two major potential risks must still be monitored to ensure rational operation:
1. Core risks: macro interest rate signals and resistance level selling pressure
Macroeconomic interest rate risk: If the Federal Reserve releases signals of 'further interest rate hikes', it could trigger a collective pullback in risk assets, and BTC, as a 'high-risk asset representative', may be affected. Close attention should be paid to the speeches of Federal Reserve officials and economic data tonight;
Resistance level selling pressure risk: There may be dual selling pressure around 117878 USD from 'previously trapped positions being released + short-term profit-taking', if the breakthrough occurs with insufficient trading volume, a 'false breakout' could occur; it is necessary to wait for 'stabilizing at the resistance level + volume confirmation' before adding positions.
2. Operational principles: do not blindly chase highs, rely on support levels for layout
In the short term, it is necessary to avoid 'blindly chasing highs due to strong market trends', especially when approaching the 117878 USD resistance level. It is necessary to wait for a pullback to the support level before entering; if the resistance level is directly broken, a 'tiered buying' strategy can be adopted (such as first building a 30% position after the breakthrough, and then adding 20% after stabilizing), avoiding the risk concentration caused by entering at a single price level.
The current BTC 4-hour K-line volume-price resonance and technical indicators form a 'bullish resonance'. The probability of a short-term breakthrough of the 117878 USD resistance level is relatively high, but it is necessary to rationally cope with the fluctuations during the process. Only by firmly grasping the core strategy of 'support level layout and resistance level profit-taking' can one maximize profits in a strong market.
