Julia's coding blog - Practice makes perfect

From January 2015, she started to practice leetcode questions; she trains herself to stay focus, develops "muscle" memory when she practices those questions one by one. 2015年初, Julia开始参与做Leetcode, 开通自己第一个博客. 刷Leet code的题目, 她看了很多的代码, 每个人那学一点, 也开通Github, 发表自己的代码, 尝试写自己的一些体会. She learns from her favorite sports – tennis, 10,000 serves practice builds up good memory for a great serve. Just keep going. Hard work beats talent when talent fails to work hard.

why smc concept has no things like FVG to cover gap-up in two bars

The Smart Money Concepts (SMC) framework doesn't have a specific tool for "gap-ups in two bars" because a standard Fair Value Gap (FVG) already accounts for this structure.

In a traditional three-bar FVG, the gap is measured between the wick of Bar 1 and the wick of Bar 3. However, when an actual market gap-up (or gap-down) occurs between two consecutive bars, SMC handles it through specific price action rules rather than inventing a new term.

Here is exactly why SMC handles a two-bar gap without a unique acronym:

1. The Opening Gap Is an Automatic Void

When a market closes at one price and gaps up significantly on the very next bar's open, the entire space between those two bars contains zero trading volume.

SMC Rule: In SMC, this is treated as the ultimate form of imbalance or a liquidity void.

The "Invisible Bar": Many SMC traders mentally treat a massive two-bar gap as if there were an invisible, ultra-aggressive momentum bar between them. Because the algorithm delivered price inefficiently without offering bidirectional trading, the market views the entire gap space as an unfilled target that price will eventually want to reprice (fill).

2. It Usually Disappears on Lower Timeframes

SMC relies heavily on fractal market structure (looking at the same price action across different timeframes).

A clean two-bar gap-up on a Daily chart or a 4-Hour chart doesn't look like a two-bar gap if you zoom in.

If you drop down to a 15-minute or 5-minute timeframe, that sudden overnight or session gap is represented by a rapid, consecutive series of aggressive, large-bodied candles.

On those lower timeframes, standard three-bar FVGs will naturally form all the way up the move. Therefore, a separate "two-bar FVG" concept is redundant.

3. How to Draw the Inefficiency in a Two-Bar Gap

If you are looking at a chart where price gaps up from Bar 1 to Bar 2 without a third bar yet, SMC traders map the imbalance like this:

For a Gap-Up: The area of imbalance is measured from the High (or Close) of Bar 1 to the Low (or Open) of Bar 2.

The Result: This creates a visual box of delivery inefficiency. Because it functions identically to an FVG (a magnet for future price to retest and mitigate), traders simply label it a Liquidity Void or an Imbalance (IMB) rather than overcomplicating the terminology.

Are you seeing these two-bar gaps on daily stock charts (overnight gaps) or on crypto/forex intraday charts? If you share the specific market you are trading, I can explain how to find the hidden FVGs inside those gaps.

most affected stock because of today interest rate hiking 0.25, ORCL stock or other stocks like huge debt. In Cihnese

在美联储（Fed）主席凯文·沃什（Kevin Warsh）宣布**加息25个基点（0.25%）**并将联邦基金利率推高至 3.75%–4% 的目标区间后，市场情绪因其释放的鹰派信号而显著承压，三大股指集体回落（道指收跌逾600点）。 [1, 2, 3, 4]

相比于甲骨文（ORCL）这类具有强劲人工智能驱动增长和现金流支撑的科技巨头，今天受加息冲击最严重的绝非 ORCL，而是那些严重依赖浮动利率、面临即期债务展期压力以及对借贷成本极度敏感的高负债和传统顺周期板块股票。 [1, 2]

🔎 为什么高负债股票比 ORCL 受伤更重？

加息直接推高了美国国债收益率，10年期美债收益率再度突破 5% 大关。这导致了清晰的风险分化： [1]

甲骨文（ORCL）等AI科技股：虽然高利率通常会压缩科技股的远期估值，但当前科技板块（如 Nvidia、AMD 等）受人工智能经济效益的实质支撑，表现相对具有韧性。甲骨文拥有极其稳健的商业软件订阅现金流，加息对其基本面的短期破坏性有限。

高负债/僵尸企业（Huge Debt Stocks）：这些企业是加息的直接牺牲品。随着无风险利率上升，它们的再融资成本（展期债务）将呈指数级增长，直接侵蚀净利润，甚至引发偿债危机。 [1, 2]

📊 今天受加息冲击最严重的板块与核心股票

加息通过借贷成本暴增和经济增速放缓两条路径对市场进行绞杀，以下是今天跌幅最深、受影响最大的股票类型： [1, 2]

受冲击核心板块	核心受害资产/股票代表	为什么今天跌得最惨？（加息逻辑）
重资产与运输物流	J.B. Hunt Transport (JBHT) (今天标普500指数中跌幅最大，暴跌 13%)	致命组合：高成本 + 需求放缓。其CFO明确警告三季度利润将大跌。加息直接增加了供应链资本开支，同时抑制了实体经济对物流运输的总需求。
传统银行业与金融	摩根大通 (JPM) (收跌 2%，成为大盘最大拖累之一)	收益率倒挂与贷款萎缩。 2年期美债收益率飙升至 4.73%，长短期利差收窄。高利率吓退了购房者和企业贷款需求，缩减了银行利差利润。
高负债/高杠杆传统企业	公用事业、电信巨头、未盈利中小盘股（如罗素2000成分股）	债务爆雷风险。随着10年期国债收益率重回 5% 以上，这些背负数百亿固定资产债务的企业在面临债务到期时，不得不以更高的利息发行新债，极易引发评级下调。
高对冲风险资产	高度依赖借贷的房地产信托（REITs）	借贷成本暴增导致并购和开发停滞，同时5%的无风险国债收益率让高股息的 REITs 失去了吸引力。

💡 投资者战略框架与风险防范

面对美联储 unanimous（12-0一致通过）的鹰派加息以及年内可能再次加息的预期，建议您对高负债资产采取以下风险对冲审视： [1, 2]

全面排查垃圾债（Spreading Risk）：坚决避开净债务/EBITDA 比例过高（通常大于 4x）且自由现金流为负的僵尸企业。高利率持续的时间越长，这类企业爆雷或被清算的概率越高。

拥抱“现金王”：将持仓向防御性、低波动、高现金流的资产倾斜。甲骨文（ORCL）在这类环境中反而因其强大的企业客户粘性，比那些无盈利、高负债的投机性股票安全得多。 [1]

Sept.15 2026 | Margin account | AMD, Meta trade review

Trade review - AMD

Work on AMD stock - EMA 100 day chart rebound - 10% gain - Should trade and hold for 3 to 4 days

It is important for me to learn how AMD stock is in very strong uptrend once after EMA 100 test on Sept. 3 2026. It took 3 days to go uptrend with 15%, 68 dollars gain. I traded 50 shares, so the gain can be maximized up to 50 x 68 = $3400 in three days.

Do not underestimate the uptrend momentum as AMD market of GPU is hugh market specially after CFO of AMD made some annoucement of adding of GPU market.

Trade review - META

Sept 2 Day chart - Far beond EMA 5 on day chart, Sept 3 as well - The momentum is so strong and then allow traders on Sept. 3 and 4 to catch uptrend crossed up EMA 200 line - blue line - another 2 day rest for another uptrend.

Just read the day chart and it is easy to tell that strong uptrend momentum took META stock 3 days to crossed up from EMA 100 to EMA200, and then before that META stock went up above EMA 5 on Sept 2 and then huge gap-up on Sept 3.
