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.

NVDA stock | D chart | How to analyze EMA 100 to EMA 50 - Big institutional buy area | How to make money from NVDA?
EMA 100 > EMA 200
I asked Google AI and how to trade NVDA stock using day chart.

Add EMA 20 on the chart
5 min scalping strategy CSCO on earnings dip on August 14, MACD show 5 min pivot point correctly, but I took early 1 min chart early time not bottom yet, I am back testing 5 min scalping, using VWAP EMA 9 21, MACD, marketsmith vol indicator, any good indicator to match MACD signal buy entry? in Chinese please
在 5 分钟超短线(Scalping)策略中,利用 1 分钟图提前进场往往会因为左侧摸底而遭遇假突破,导致过早止损。
- 作用:Stochastic RSI 比普通 RSI 更敏感,是 5 分钟超短线抓动能反转的利器。
- 过滤假信号:当 1 分钟或 5 分钟的 MACD 出现金叉意图时,必须等待 Stochastic RSI 在超卖区(低于20)完成 %K 线向上突破 %D 线的金叉。
- 实战配合:价格在 VWAP 下方远离时,MACD 柱状图开始缩短,若此时 Stochastic RSI 从底部金叉抬头,通常是极其精准的低风险右侧买点。 [1]
- 作用:财报日剧烈波动时,寻找价格的极端边界(极限开外)。
- 多空精确定位:在财报大跌中,股价常常会跌穿布林线或 Keltner Channels 的下轨。
- 买入触发:单看 MACD 金叉很容易在阴跌中被骗。完美的买入点是:5分钟K线跌出下轨后,重新收盘收回下轨线内部,且此时 MACD 柱状图出现底背离(Price lower low, MACD higher low)。这能确保你不会在 1 分钟图上盲目猜底。 [1]
- 作用:ADX 用来衡量趋势的强度(无论长跌)。
- 捕捉动能枯竭:在 CSCO 财报跳空低开并快速下砸的过程中,ADX 指数会飙升(通常高于 40-50 表明下跌动能极强)。
- 配合金叉:不要在 ADX 还在往上飙升时接飞刀。当 ADX 在高位见顶开始向下折返(表明砸盘动能衰竭),同时 MACD 慢线在零轴下方趋于平缓或形成金叉时,才是高胜率的超短线做多时机。
- MACD 参数调整:传统的 (12, 26, 9) 在 5 分钟和 1 分钟超短线中严重滞后。建议在回测中尝试更灵敏的设置,例如 (8, 17, 9) 或 (5, 35, 5),以提高右侧进场的时效性。
- 多周期共振(不要单独看 1 分钟):既然 5 分钟的 Pivot Point 是对的,在 1 分钟找具体买点时,1 分钟的 EMA 9 必须重新站上 EMA 21。如果 1 分钟的 K 线依然在 EMA 9 之下被死死压制,即使 MACD 看起来要金叉,也绝不提前动手。 [1]
Set up tradingview template to test EMA 200, 100, 50, 21, 9, 5, so I can find easy target to trade top big companies when testing EMA 200, EMA 100, I learned that uptrend EMA 200 is important, eMA 50 is to add in uptrend for big institutional buyers, EMA 5 for MU stock this year 249% gain in 44 days starting from April 1, can you help me to set up templates, so far, D chart there are six, EMA 5, 9, 21, 50 100, 200, what do you have for me to find good low risk trades?
To trade large-cap companies effectively without cluttering your daily chart, you should consolidate your six indicators into a single custom script and follow a structured low-risk checklist. Relying on six individual moving averages wastes indicator slots and makes your workspace messy.
- Open your chart on TradingView.
- Click the Pine Editor tab at the bottom of the screen.
- Delete any default code and paste the script below.
//@version=5
indicator("Custom 6-EMA Multi-Pack", overlay=true)
// Inputs for EMA lengths
ema5_len = input.int(5, title="Fastest Momentum")
ema9_len = input.int(9, title="Short-term Trigger")
ema21_len = input.int(21, title="Pullback Guide")
ema50_len = input.int(50, title="Institutional Support")
ema100_len = input.int(100, title="Trend Transition")
ema200_len = input.int(200, title="Line in the Sand")
// Calculations
ema5 = ta.ema(close, ema5_len)
ema9 = ta.ema(close, ema9_len)
ema21 = ta.ema(close, ema21_len)
ema50 = ta.ema(close, ema50_len)
ema100 = ta.ema(close, ema100_len)
ema200 = ta.ema(close, ema200_len)
// Plots with visual hierarchy (Thin/Light for fast, Thick/Bold for institutional)
plot(ema5, color=color.new(#FF5252, 0), linewidth=1, title="EMA 5")
plot(ema9, color=color.new(#FF9800, 0), linewidth=1, title="EMA 9")
plot(ema21, color=color.new(#FFEB3B, 0), linewidth=1, title="EMA 21")
plot(ema50, color=color.new(#00E676, 0), linewidth=2, title="EMA 50")
plot(ema100, color=color.new(#29B6F6, 0), linewidth=2, title="EMA 100")
plot(ema200, color=color.new(#3F51B5, 0), linewidth=3, title="EMA 200")
- The Blueprint: Only trade companies where the current daily price sits safely above a rising EMA 200 and EMA 100.
- Setup A: The Mean Reversion Pullback
- Look for a strong stock in a clear uptrend that experiences a brief market pullback.
- Wait for the price to fall back and stabilize exactly at the EMA 21 or EMA 50.
- The Entry: Buy the moment a daily candle finishes green after testing the moving average. Place your stop-loss order just underneath that structural support level. [1, 2, 3]
- Setup B: The Velocity Momentum (The "MU Model")
- Watch for high-alpha megacaps that are actively breaking out of multi-week consolidations.
- The Entry: Enter the trade when the EMA 5 crosses cleanly over the EMA 9.
- The Trailing Stop: Ride the velocity wave. Aggressively trail your stop-loss right below the EMA 9 or EMA 21 on a daily closing basis. Exit immediately when a daily candle breaks and closes below that line.
- Set your primary universe filter to S&P 500 or large-cap companies.
- Head over to the technical filters and input these rules:
- Save this configuration as your custom blueprint to instantly pinpoint names primed for institutional bounces.
