Nice to meet you. Thank you for viewing my profile. I am Shinryu, the head of ShenLong Lab (Shenron Lab). I learned programming to become a trader. Before studying market methods, I decided to acquire the ability to create the tools that support trading by myself. With that determination, I paid 2,000,000 yen for a programming school, and that was the start. Now, as an active trader who uses my own indicators in daily trading, I have developed over 1,000 financial indicators and automation tools to date. What is truly needed to face the markets for a long time is not complex logic. It is “visualization that eliminates hesitation” and “thoroughly efficient verification work.” ShenLong Lab indicators are all created to solve things I personally felt were hard to see or tedious in trading. They make work easier, reduce stress, and allow you to focus on analysis and trading itself. I have crafted them into tools that you can feel the change in on your daily charts. All parameters are labeled in Japanese, and you can select them with “ON/OFF” instead of true/false, so even without specialized knowledge you can set them without hesitation. The logic that can be verbalized resides in the code. I will continue to develop tools that translate trading intuition and stress into words, reduce manual waste, and maximize the results of thinking and trading. I hope ShenLong Lab indicators will help make your trading more comfortable for everyone. *Investment results are not guaranteed.

The point where Episode 23 reaches ±3σ is obvious at a glance. Marking the overextensions of the Bollinger Bands with SL_B3S

ShenLong Lab's Shenlong.
For first-time visitors, please allow me to introduce myself a little.
As a active trader who continually generates monthly profits with my own indicators, I have developed more than 1,000 indicators and automation tools to date.

ShenLong Lab's second project, the eighth item of "Market Compass"
"SL_B3S (Bollinger 3 Sigma)"
has been released.

This time, I will talk about the reason I created this item and tips for checking Bollinger Band ±3σ touches in MT4/MT5.

Is that wick reaching ±3σ?

The ±3σ of the Bollinger Bands is the outermost line, which the price hardly reaches.
Where it does reach becomes a guide of excessive price movement.

Whether the wick tip touched ±3σ can be hard to determine unless you zoom in on the chart.

Personally, I used to compare the candle wick with the line by bringing my eyes close.

A workaround with standard features
  • Set Bollinger Bands to only ±3σ and reduce the number of lines
  • Highlight only the ±3σ line by changing its color and making it thicker
  • Zoom in on the chart to confirm the overlap of wick and line

All of these ultimately come down to visually comparing by eye.

If it reaches ±3σ, it’s fine to mark it.

That was what I created SL_B3S for.

From here on, I will introduce how to use SL_B3S in a video.
