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.

This scenario describes aCovered Callstrategy. You have purchased 100 shares of Zscaler (ZS) at $175 and sold (written) one call option at a $175 strike price for a premium of $9 per share.
Because the strike price ($175) is the same as your purchase price, this is an At-The-Money (ATM) covered call, which acts as a conservative income-generation strategy.
Net Cost Basis: $175 - $9 = $166 per share ($16,600)
Potential Scenarios (as of Feb 27 Expiration)
1. The Ideal Scenario: Stock Stays Flat (Closed at $175)
Outcome: The option expires worthless. You keep your 100 shares and the $900 premium.
Profit: $900.
Return: 5.14% in 10 days (assuming premium).
2. The Bullish Scenario: Stock Rises Above $175
Outcome: Your shares are "called away" (sold) at $175.
Profit: You make $0 on the stock ($175 - $175), but you keep the $900 premium.
Result: You still make $900, but you miss out on any gains above $175.
3. The Bearish Scenario: Stock Falls Below $175
Outcome: The call expires worthless. You keep the $900 premium, but the value of your shares decreases.
Breakeven Point: Your effective breakeven is $166 ($175 purchase - $9 premium).
Result: You only begin to lose money if ZS falls below $166 by Feb 27. If it drops to $160, you have a $500 loss on the stock, but it's offset by the $900 premium, resulting in a $400 net profit.
Key Takeaways
Maximum Profit:$900 (occurs if ZS closes at or above $175 on Feb 27).
Maximum Loss: Occurs if ZS drops to $0. The maximum loss is your breakeven ($166) times 100, which is $16,600.
Why it was done: This strategy is used to generate income ($900) while accepting that potential upside is capped at $175, while also providing a small buffer against a stock price drop.
In Smart Money Concepts (SMC), understanding the difference between aHigher High (HH)and aLower High (LH)is fundamental to identifying trend direction, whileFOMO(Fear of Missing Out) represents the psychological trap that causes retail traders to trade against institutional logic.
Here is a detailed breakdown of HH vs. LH and how FOMO relates to these structures.
1. HH (Higher High) - Bullish Structure
Definition: A swing high that breaks above the previous swing high.
Significance: Indicates a bullish market structure and strong momentum.
SMC Interpretation: Institutions are driving the price up, creating demand zones.
Action: Traders look for Buy opportunities (Longs) at the newly created Higher Low (HL) or within an Order Block (OB) below the HH.
FOMO Risk: Buying blindly as the price makes a HH, without waiting for a retracement (pullback) to a "Discount" zone, often leads to buying the top before a correction.
2. LH (Lower High) - Bearish Structure
Definition: A swing high that fails to break above the previous high, setting a new high below the last one.
Significance: Indicates a potential trend reversal or continuation of a bearish trend (LL + LH sequence).
SMC Interpretation: Institutions are failing to push prices higher, or are actively selling, creating supply zones.
Action: Traders look for Sell opportunities (Shorts) at the Lower High.
FOMO Risk: Panicking and selling at a lower high just before a "stop hunt" or "liquidity grab," where institutions briefly push the price up to sweep stops before dropping it.

3. The FOMO (Fear of Missing Out) Connection in SMC
FOMO occurs when traders, seeing a rapid HH or a sudden LH, disregard their trading plan to enter the market immediately. SMC highlights how institutions exploit this behavior.
HH FOMO (The "Too Late" Buy)
Scenario: Price makes a massive impulsive move up, creating a new HH.
FOMO Behavior: Retail traders fear missing the trend and buy immediately at the peak.
SMC Reality: Institutions have already created their Order Block (Demand Zone) lower down. The price will likely retrace to that zone to fill the Fair Value Gap (FVG) before continuing, causing the FOMO buyer to be stopped out.
LH FOMO (The "Panic Sell" Trap)
Scenario: Price is trending down, making a LH.
FOMO Behavior: Seeing a sharp drop, traders FOMO sell (Short) at the bottom of the move, just as price hits a demand area.
SMC Reality: Smart money often uses liquidity grabs (stop hunts) to create a false breakout above a previous LH, trapping sellers, before reversing the trend (CHoCH).
How to Avoid FOMO with SMC
Wait for Mitigation: Never enter on the impulsive move. Wait for price to return to an Order Block (OB) or Fair Value Gap (FVG) to "mitigate" (rebalance) the market.
Use Premium/Discount Zones: Only buy (HH) in the discount zone (below 50% of the swing) and sell (LH) in the premium zone (above 50%).
Confirm with CHoCH: Wait for a Change of Character (CHoCH) on lower timeframes to confirm that a structure shift is genuine, rather than a liquidity grab.
