Hello,
After releasing the free grid visualizer “Grid Imaginative and prescient TP&NP”, I needed a easy instrument that tells me
“is the market calm or harmful proper now?” at a look – particularly when working grid / martingale EAs or scalping GOLD. :contentReference[oaicite:0]{index=0}
That’s why I made this free indicator:
==================================================
Free MT4 Indicator – Drop & Volatility Defend Monitor
==================================================
This indicator exhibits a small standing bar on the high of the chart, like:
Drop Defend: NORMAL | ATRx1.05 | Spr: 0.30/0.60
The textual content coloration modifications in response to market situations: :contentReference[oaicite:1]{index=1}
– 🟩 **NORMAL** – common market situations, “enterprise as common”
– 🔴 **COOL** – excessive volatility or sudden drop / unfold spike detected → “settle down”
– 🟧 **RECOV** – market is recovering after a unstable interval
Moreover, when the indicator detects a brief burst of consecutive bearish M1 candles,
it internally enters a **FREEZE** state.
In FREEZE time you often don’t need to add severe new positions.
The concept is to not generate entries, however to visualise *once we ought to decelerate or pause*.
————————————————–
Core logic (simplified)
————————————————–
1. **Drop filter (ΔClose on greater timeframe)**
– Displays the final 2 closed candles on a selected timeframe (default: M15).
– If the close-to-close distinction is larger than `DropThreshold_USD`, the standing turns into **COOL**.
– Instance: `DropTF = M15`, `DropThreshold_USD = 10.0` →
if M15 shut drops greater than 10 USD, we regard it as a harmful transfer.
2. **ATR primarily based volatility filter (M1)**
– Calculates ATR on M1 with interval `ATR_Period`.
– Builds a baseline from the final `ATR_BaseBars` M1 bars.
– If the present ATR is greater than `ATR_CoolMultiplier` instances the baseline, standing switches to **COOL**
(e.g. ATRx2.5 = “2.5x regular volatility”).
3. **Unfold gate**
– If `Ask – Bid` exceeds `SpreadMax_USD`,
the standing goes to **COOL** even when candles look calm.
– This catches information spikes / low-liquidity durations the place unfold explodes.
4. **RECOV (restoration) logic**
– After a while in COOL, the state mechanically modifications to **RECOV**.
– Optionally (`RequireRebound = true`), standing solely returns to NORMAL when:
– current M1 candles are bullish,
– unfold is again under `SpreadMax_USD`,
– shut is above EMA20 + `ReboundOffset_USD`.
So the indicator tries to detect:
– sudden drops,
– irregular volatility,
– unhealthy unfold,
after which waits for an inexpensive restoration earlier than telling you “OK, again to NORMAL”.

Typical use instances
————————————————–
**1) Scalping / day buying and selling (M1–M15)**
For handbook merchants in GOLD or FX who assume:
– “I need to scale back dimension round information”
– “I don’t need to add new positions proper after an enormous dump”
You should utilize the colour as a easy rule set off:
– **NORMAL (inexperienced)** → commerce together with your common technique / dimension
– **COOL (purple)** → cease new entries, halve your lot, or keep away from counter-trend scalps
– **RECOV (orange)** → restart with smaller dimension and see if situations actually relax
**2) EA monitoring / grid methods**
In case you run grid / martingale EAs and need an additional layer of security with out touching the EA code:
– When the bar exhibits **COOL**, you may:
– briefly disable AutoTrading,
– scale back heaps,
– or keep away from turning on a brand new EA.
It’s a separate “market temper” layer that helps you determine when to be aggressive or defensive.

Enter parameters (quick overview)
————————————————–
– **UseDropFilter** – allow / disable all drop & volatility logic (true by default)
– **DropTF** – timeframe used for close-to-close drop detection (M15 really helpful)
– **DropThreshold_USD** – what number of {dollars} of drop to set off COOL
– **ATR_Period** – ATR interval on M1
– **ATR_BaseBars** – variety of M1 bars to construct the ATR baseline
– **ATR_CoolMultiplier** – required ratio vs baseline to set off COOL (e.g. 2.5)
– **SpreadMax_USD** – unfold threshold to set off COOL
– **RequireRebound** – if true, require a rebound earlier than returning to NORMAL
– **ReboundOffset_USD** – how far above EMA20 the value have to be to depend as “rebounded”
– **PanelTopCenter** – present standing bar at high heart (really helpful)
– **MinimalMode** – 1 line solely (true) or 2 strains with extra particulars (false)
– plus primary colours / font dimension choices
All cash values are in account foreign money (sometimes USD).
