[blackcat] L1 Enhanced DMI

Level: 1


The Directional Movement Index (DMI) is an indicator developed by J. Welles Wilder in 1978 that shows the direction in which the price of an asset is moving. The indicator does this by comparing previous highs and lows and drawing two lines: a positive directional movement line (+ DI) and a negative directional movement line ( -DI ). An optional third line, called the Average Directional Index ( ADX ), can also be used to measure the strength of the upward or downward trend.
When + DI is above -DI there is more upward pressure than downward pressure in price. Conversely, when -DI is above + DI, there is more downward pressure on the price. This indicator can help traders estimate the direction of the trend. Crossovers between the lines are also sometimes used as trading signals to buy or sell.

In real life, I am a prolific inventor. I have successfully applied for more than 60 international and regional patents in the past 12 years. But in the past two years or so, I have tried to transfer my creativity to the development of trading strategies. Tradingview is the ideal platform for me. I am selecting and contributing some of the hundreds of scripts to publish in Tradingview community. Welcome everyone to interact with me to discuss these interesting pine scripts.

The scripts posted are categorized into 5 levels according to my efforts or manhours put into these works.

Level 1 : interesting script snippets or distinctive improvement from classic indicators or strategy. Level 1 scripts can usually appear in more complex indicators as a function module or element.

Level 2 : composite indicator/strategy. By selecting or combining several independent or dependent functions or sub indicators in proper way, the composite script exhibits a resonance phenomenon which can filter out noise or fake trading signal to enhance trading confidence level.

Level 3 : comprehensive indicator/strategy. They are simple trading systems based on my strategies. They are commonly containing several or all of entry signal, close signal, stop loss, take profit, re-entry, risk management, and position sizing techniques. Even some interesting fundamental and mass psychological aspects are incorporated.

Level 4 : script snippets or functions that do not disclose source code. Interesting element that can reveal market laws and work as raw material for indicators and strategies. If you find Level 1~2 scripts are helpful, Level 4 is a private version that took me far more efforts to develop.

Level 5 : indicator/strategy that do not disclose source code. private version of Level 3 script with my accumulated script processing skills or a large number of custom functions. I had a private function library built in past two years. Level 5 scripts use many of them to achieve private trading strategy.

Blackcat thank you for your sharing. I have a question about DMI period and confirmation period. I am wondering why you choose 7 and 7 for them. Is there a specific reason (time period etc) for it? And the second one, is it suitable to set those periods 7 and 7 for 1 hour or 4 hours time periods?

I really enjoy your works by the way :)
