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.

Performance issues
I used the following 5 min chart and I could not determine where to sell on swing high and where to buy on swing low
I only have less than $250 dollars gain on 65 shares of INTU stock today with multiple trades.
Introduce new chart - 5 min chart
EMA percent angle / Slope Visualizer - EMA 8, degree 0.07 - Highlight using bold purple - Swing Trade
Three trades in detail view - Trade 1
Three trades in detail view - Trade 2
Three trades in detail view - Trade 3
My gain today on INTU is $120 US dollars, after this new trading system, my gain should be $1495, 1245% gain.
EMA Slope (Forex Factory/Custom Scripts)
EMA Slope indicators are tools used in Forex trading to measure the angle or rate of change of an Exponential Moving Average (EMA). A steep upward slope indicates strong bullish momentum, while a steep downward slope indicates strong bearish momentum. These are often used to identify trend strength, trend reversals, and to filter out noisy, ranging markets.
- Trend Identification: The slope direction (up, down, flat) determines the market sentiment.
- Slope Angle: A higher angle represents higher volatility and momentum, while a near-horizontal line suggests consolidation.
- Color-Coding: Custom scripts often change the color of the EMA line based on the slope angle (e.g., green for positive slope, red for negative).
- Forex Factory Threads: There are several threads discussing slope indicators, such as the "Ema slope direction line" thread, "Angle Indicator" thread, and "Trade the Slope System". These threads often provide custom MQL4/MQL5 code for MT4/MT5.
- TradingView (Pine Script):
- Slope Direction Line: These indicators plot the EMA and color it based on whether the angle is upward or downward.
- Volatility-filter: This script can be set to change colors based on the EMA slope.
- Custom EMA v2: A popular script that includes "goline price action" and visual ribbons to represent trend strength.
- 8/9 EMA: Used for fast momentum and scalping.
- 20/21 EMA: Ideal for swing trading and identifying pullbacks.
- 50 EMA: Used for intermediate trend assessment.
- 200 EMA: Used for long-term trend analysis.
- Trend Confirmation: Only taking trades in the direction of the EMA slope.
- Momentum Explosion: Using a fast EMA (e.g., 8) to cross a slower SMA (e.g., 26) when the slope is steep.
- Support/Resistance: The EMA line acts as a dynamic support (when sloping up) or resistance (when sloping down).
2026-03-03 | INTU stock | 5 min chart | First 10 bars - Should sell at No. 3 and buy back at No. 9
First 10 bars - Should sell at No. 3 and buy back at No. 9 - 65 shares
Reduce the cost of $650 US dollars
Need to add some indicator to measure uptrend or downtrend momentum on INTU stock, so I can make informed decision to trade on the top and buy back at the bottom.Indicator to measure EMA 8 uptrend angle
Several indicators exist to measure the angle or slope of an Exponential Moving Average (EMA), which helps quantify the strength of an uptrend (i.e., acceleration vs. consolidation). Key indicators for this purpose include:
- EMA Slope Angle (by xvelox_): A specialized TradingView indicator that directly measures the angle of an EMA in degrees, allowing for visualization of trend strength.
- MA SMART Angle (by Smart-Day-Trader): A sophisticated, non-repainting indicator that calculates the slope/angle of multiple EMAs (including customizable, fast, medium, and slow). It identifies uptrends when the angle exceeds a specific threshold (e.g., > 15° for strong trends).
- EMA Percent Angle & Slope Visualizer (by Ramesh_G): This indicator uses a percentage-normalized calculation, making it ideal for comparing slope strength across different assets regardless of their price scale.
- Trend Angle Indicator (by NellyNaneva): Measures the trend angle by calculating the rise-over-run of a moving average, providing visual confirmation of strong momentum (e.g., breaking above +25°), and allowing smoothing via an EMA.
- EMA Slope (Forex Factory/Custom Scripts): These custom scripts calculate the difference between the current EMA and a previous EMA, often normalizing it against price movement.
When using the 8-period EMA to measure trend strength, these indicators look for a positive angle (upward trajectory) and high steepness, which often signals a strong, sustainable uptrend.
To measure the EMA 8 angle specifically:
- Add the 8 EMA to your chart.
- Add a "Slope" or "MA Angle" indicator (e.g., "EMA Slope" by xvelox_) and set its length to 8.
- Confirm the Trend: An upward slope (positive value) with a sharp angle indicates strong momentum.

5 Key Strategies to Minimize Trading Losses | ShadowTrader Weekend Edition 12/13/2024
Here is the link.

- Leverage complex structures to your advantage so that all in stances of being wrong translate into break evens or tiny losses.
dcc candlestick pattern 如何使用
在技术分析中,DCC (Dark Cloud Cover),即乌云盖顶,是一种由两根 K 线组成的看跌反转形态。它通常出现在一段上升趋势的顶部,预示着上涨动力减弱,价格可能转向下跌。
- 前提趋势: 必须出现在明确的上升趋势中。
- 第一根 K 线: 是一根强劲的大阳线(白色或绿色),显示买方依然占据主导。
- 第二根 K 线:
- 跳空高开: 开盘价高于前一天的最高价或收盘价(反映了市场最后的冲刺力量)。
- 深跌回补: 随后价格回落,收盘价必须跌破第一根阳线实体的中点(50%),但通常不跌破第一根线的开盘价(否则就变成了看跌吞没形态)。
- 入场信号: 乌云盖顶本身是一个警示信号。稳健的交易者通常会等待第三根 K 线确认(即第三根线继续收低)后再考虑做空。
- 设置止损: 止损点通常设在第二根阴线的最高价之上。
- 结合辅助指标:
- 阻力位: 如果形态出现在关键的阻力位附近,可靠性更高。
- 超买信号: 配合 RSI 或 随机指标 的超买信号使用,效果更佳。
- 成交量: 第二根阴线的成交量越大,转势信号越强烈。
- 时间框架: 在日线或周线等较高时间框架上更为可靠。
- 不可单独使用: 乌云盖顶可能出现虚假信号,应结合整体趋势和风控措施。
- 相反形态: 它的看涨对应版本被称为刺透形态 (Piercing Pattern)
