HuiYing Quant v2.10 MT5 Source Code

Product Intro
HuiYing Quant is an MT5 two-way grid trading system.
Long/short open independently, averaging by a custom lot sequence with grid spacing dynamically contracting as order count grows.
Built-in single-order TP, cross-two-order TP, total average TP, total SL, profit protection, auto lock, closed-profit labels — with a black-gold panel and one-click buttons, good for markets alternating range and trend.

Featured: auto-lock & auto-unlock

Core Features
1. Two-way Grid + Custom Lots
Long/short open independently, counted per side.
Lots configured as a string list, taken sequentially; capped at max lot after exhaustion.
First lot, max lot and lot sequence all adjustable.

2. Dynamic Grid Spacing
Base spacing configurable, default 100 points.
After one-side order count passes a set value, spacing auto-contracts.
Contraction ratio and spacing floor adjustable, preventing over-dense later averaging.

3. Multi-level TP
Single-order TP: close when single profit reaches lot × single-TP.
Cross-two TP: when first + middle order average profit hits threshold, close the two together.
Total average TP: by direction average + target amount, whole side.
Current-max-lot TP: close that side when lot hits threshold and profit target met.

4. Multi-layer Risk
Total SL: close all when long+short combined floating loss hits amount threshold.
Floating-loss breaker: after one-side floating loss hits N% of equity, stop that side's averaging.
Profit protection: when price nears the average-TP price, auto-move SL to lock profit.
Market-closed guard: cool down 120s and retry on closure or insufficient margin, avoiding log spam.

5. Auto Lock (anti-ratchet)
Total floating loss hits threshold → auto-open reverse lock orders, freeze grid.
Price first reverses a confirm distance, then returns to entry → auto-unlock.
Second lock needs price to reverse far enough again, preventing churn locks.
Unlock floating-loss recovery ratio and post-unlock freeze seconds adjustable.
Force-unlock after max lock days (0 = unlimited).

6. Closed-profit Labels
Each close annotates profit amount on the candle.
Rounded-corner block + bold white text, emulating a pro terminal.
Multiple orders closed at the same instant → merged into one total label.
Single labels and batch labels keep the latest N each.
