[Unlimited Grid] What Is “Maintained Value”?

In Unlimited Grid Trading, “Maintained Value” is the core concept that ensures capital safety, while “never selling out of the base asset” is the key mechanism that keeps the strategy stable and secure.
Both are fundamental to protecting user assets and achieving consistent long-term returns.

1. Definition and Logic of “Maintained Value”

Maintained Value means that during the operation of an Unlimited Grid strategy — as long as the token price remains above the lower limit — the system automatically performs “buy low, sell high” actions to keep the total value of the user’s base asset (e.g., BTC, ETH) equal to the initial investment amount.
This ensures that the value of the core asset doesn’t shrink when the price falls, nor diminish when the price rises.

Example:

• Suppose a user starts an Unlimited Grid strategy when BTC = 10,000 USDT, investing 10,000 USDT to buy 1 BTC.
  The maintained value is therefore 10,000 USDT.

When the price rises:
If BTC increases to 10,100 USDT (+1%), the system automatically sells 100 USDT worth of BTC (≈ 0.0099 BTC).
The user now holds 0.9901 BTC, worth about 0.9901 × 10,100 = 10,000 USDT — maintaining the same total value.
The sold 100 USDT becomes realized profit, which can later be withdrawn.

When the price falls:
If BTC drops back from 10,100 USDT to 10,000 USDT, the system uses the previously realized 100 USDT to buy back 0.01 BTC.
Holdings return to 1 BTC, and the total value remains 10,000 USDT.

In simple terms, Maintained Value acts as a “value anchor” for your portfolio:
No matter how the price fluctuates, the base asset’s total value stays locked around the initial investment.
The system continuously converts price volatility into realized profits — preserving capital while generating steady income.

2. Why the Strategy “Never Sells All Base Assets”

A defining design principle of Unlimited Grid Trading is to hold the base asset long-term, not to liquidate it.
Therefore, the system is structured to avoid selling all assets, for two main reasons:

(1) Strategy logic limitation:
The Unlimited Grid only sells the appreciated portion of the base asset — not the entire holding.
For example, if the user initially holds 1 BTC (worth 10,000 USDT), each 1% price increase triggers the sale of BTC worth 100 USDT (≈ 0.0099 BTC).
After selling, the remaining 0.9901 BTC still equals roughly 10,000 USDT in value.
Even if BTC rises to 20,000 USDT, each trade still only sells the portion worth 100 USDT (≈ 0.005 BTC).
Thus, the majority of the base asset remains intact and is never fully sold.

(2) No upper price limit — continuous order placement:
Since Unlimited Grid has no upper price boundary, the system keeps placing new sell orders at higher prices (e.g., at 30,300 USDT, 30,603 USDT, etc., as BTC climbs).
However, each order only sells the excess amount above the maintained value, not an increasing quantity — ensuring that the base asset balance always remains.

3. Rare Cases Where All Base Assets Might Be Sold

Although “selling all base assets” is extremely unlikely, it could theoretically occur under technical trading limits rather than strategy logic.
The two possible edge cases are:

(1) Remaining base asset is below the minimum order quantity:
Every trading pair has a minimum order size (or “quantity precision”).
For instance, BTC/USDT may require at least 0.0001 BTC per order.
If repeated arbitrage trades reduce your remaining BTC to 0.00005 BTC, the system can no longer place a sell order (since it doesn’t meet the minimum size).
In this case, the small leftover balance cannot be traded — but it’s not completely sold out; it simply remains idle.

(2) Remaining base asset value is below the minimum order amount:
Some exchanges require a minimum order value (e.g., at least 10 USDT).
If your remaining BTC is only worth 5 USDT, even if the quantity meets precision requirements, the system cannot create new orders.
Again, this doesn’t mean all assets are sold — only that the small remainder cannot participate in further trades.

Note:
These cases typically occur only under long-term, high-frequency arbitrage with very small balances.
For major coins such as BTC or ETH — where the initial investment is usually substantial — it’s extremely rare for the remaining balance to fall below precision or minimum trade limits.
Hence, users generally don’t need to worry about the system selling all their base assets.
