Sometimes when trading contracts, it makes people anxious, so I prefer to use Grid Trading.

Every time I see a bunch of numbers in the parameters of "Contract Grid / Linear Grid", it's really easy to get confused.
In fact, whether grid trading can be profitable depends 90% on three key parameters:

✔ (1) How to choose the interval

✔ (2) How to choose the number of grids

✔ (3) How to match position size and leverage

Here, I'll give you the simplest "one move to master" universal setting method, which can be used for TSLA, BTC, ETH, DOGE, and gold.
If you follow the "Fool's Three-Step Method", you won't step on a landmine and it's easier to make money.

⭐ 1. The most important thing is: Range selection method (always prioritize this)

Always remember one principle: the range should cover the highest and lowest points of the last 30 days.

Why?
Because grid trading only makes a profit when it oscillates back and forth within a "range."

> If the range is too narrow → Once it breaks through → No profit, or even a loss.
If the range is wide enough → whether it rises or retraces → it can still yield profits.

✔ Most stable range: Highest price in the last 30 days ±5% ~ Lowest price in the last 30 days ±5%

For example:

The lowest price of TSLA in the last 30 days = 400

The highest price of TSLA in the last 30 days = 520

The interval should be set as:
380 ～ 550 (or 370 ~ 560)

This way, your grid will always "wrap around the market."

⭐ 2. How to set the number of grids (determines whether your profit is more or less)

You will always remember one thing:

> The greater the volatility → The fewer the grids (10-40 grids)
The smaller the fluctuation → the more grids (40 to 120 grids)

Quick Judging Method:

Variety Grid Trading Quantity

BTC / ETH / TSLA (moderate to high volatility) 40~80 grids
Gold (low volatility) 80-150 grids
Altcoins (highly volatile) 20-40 grids

Your previous question was actually:
Too many grids → Mosquito leg profit + fees eaten away
Too few grids → No grid triggered → No profit

I will help you assign "golden grid numbers" for each variety.

⭐ 3. Position Size & Leverage (Determines Risk)

Always remember this sentence:

> The larger the leverage → The larger the range must be
The more positions you have → the easier it is to get liquidated → the range must be larger

General Security Settings:

Leverage Interval Suggestions

10x normal range is fine
20x Range expansion 10%
50x Range expanded by 20%
75x Range expansion 30~40%

If you use 50x or 75x Grid Trading:
Small range = liquidation
Range large = Safe + Make money

⭐ I'll give you a "universal template" directly, you can just follow it.

No matter TSLA / BTC / ETH / DOGE, you just need to change the numbers:

---

🧩 Universal Contract Grid Trading Template (You always follow this)

【1】Interval Selection Method (Most Important)

Upper limit = Highest price in the last 30 days * 1.05

Lower limit = Lowest price in the last 30 days * 0.95

[2] Number of Grids

High volatility: 40 to 80 grids

Low volatility: 80-150 grids

【3】Leverage & Margin

The higher the leverage → the wider the range, for example, 50x needs to be expanded by 20%.

The more margin, the safer.
