Facade: provides a consistent interface for a group of interfaces in the subsystem. This mode defines a high-level interface, which makes the subsystem easier to use.Mode description:SubSystem (SubSystem)Responsible for handling complex logic
Types of moving AveragesThe moving average can be divided into "arithmetic moving average", "weighted moving average", "exponential smoothed moving average" three kinds.1. Arithmetic moving average (MA)The arithmetic moving average is a simple and
Moving Average convergence and diver-gence)
Similar to moving average indicators, the difference is that the exponent needs to be processed smoothly. In the application, macd should first calculate the moving average value of the fast (12-day)
First nonsense: Before coming to the company, the project is done by the outsourcing company, interview at the beginning, no contact with too much time figure K line this piece, feel very difficult, I can handle not! But after a period of time,
Ma/sma/dma/ema moving Average algorithm Formula 1, simple moving average MA usage: MA (x,n): X's N-day simple moving Average algorithm (X1+X2+X3+...+XN)/n2, moving average SMA usage: SMA (X,N,M), N-day moving average for x, m/ N is the weight given

TensorFlow Neural Network Optimization Strategy Learning, tensorflow Network Optimization
During the optimization of the neural network model, we will encounter many problems, such as how to set the learning rate. We can quickly approach the optimal
This example, through numpy analysis of stock price CSV file reading and writing
CSV (comma-separated value, comma separated values) is a common file format, usually the database is the file is a CSV format, each field in the file corresponds to the
MACD called is developed from a double exponential moving average, with a fast exponential moving average (EMA12) minus the slow exponential moving average (EMA26) to get the fast line dif, then 2x (Fast line Dif-dif's 9th weighted moving
One setting of basic technical analysis parameters I have made some necessary changes to the technical parameters of the Money Dragon dynamic. : 1, EMA system Parameters Day candlestick three 5, 10, 30 is changed to 10, 15, 21. 30 the three 5,
Basic usage 1. macd Golden Cross: Diff breaks through the DEA from bottom up, which is a buy signal. 2. macd dead cross: Diff breaks through the DEA from top to bottom to sell signals. 3. macd green to red: The macd value changes from negative to
TensorFlow implements Batch Normalization,
I. BN (Batch Normalization) Algorithm
1. Importance of Data normalization
The essence of the neural network learning process is to learn Data Distribution. When training data is different from test data
Parameter Selection via exponential moving Average
When training a classifier via gradient decent, we update the current classifier ' s parametersθθviaθt+1=θt+αδθt,θt+1=θt+ Αδθt,
Whereθtθt is the ' parameters andδθtδθt is the ' update step proposed
Here's the book.
No matter what the stock, before buying shares, first look at the 250-day average, only buy 250 moving averages above the stock, preferably in the stock price from under the 250 ema across to the 250 ema when buying
