Five bars against twenty-one is a wide ratio, and that is the whole design. The scalper vault indicator lets the quick average move freely while the slower one holds its ground, then marks the bar where they finally cross. Two inputs govern the calculation; everything else routes messages.
This build ships as a compiled .ex4 for MT4 and .ex5 for MT5.
| Platforms | MT4 (.ex4) + MT5 (.ex5) |

| Inputs | 8 |
Colours, widths and shapes
Two arrow plots and nothing else.
`Scalper Buy` prints yellow using arrow 233.
`Scalper Sell` prints deep pink using arrow 234.
Each mark clears the candle by half its travel.
Neither average reaches a visible buffer.
No pane opens underneath the chart.
- Scalper Buy: arrow, yellow, arrow code 233
- Scalper Sell: arrow, deep pink, arrow code 234
How the plots get their values
Both built in the file
`FastEma` `5` and `SlowEma` `21` each run their own recursion here. The first bar seeds both with the close, after which each value leans on the one before it.
A wide ratio
Four times the length separates them. The quick average tracks price almost exactly while the slow one barely moves, so a crossing needs a genuine change of pace.
Where the mark lands
The bar’s travel decides it. A buy drops below the low by fifty percent of that candle’s high-to-low distance, so a violent bar pushes its mark further out than a quiet one.
Interpreting what you see
A wide ratio means fewer crossings than a narrow one.
Neither line is visible, so context stays hidden.
Mark colours here are unusual; read the arrow shape.
Yellow points up and is the buy.
Nothing spaces repeated marks apart.
Warm-up needs about twenty-two bars.
Alert channels in this build: popup, push notification, email and sound, one message per closed bar.
A crossing is the one reported event. `EnableAlerts` is the master switch and the terminal already throws up a dialog. The mobile ping, the mail note and the speakers reaching for `SoundFile` each begin closed.

Timeframes worth trying
A five and twenty-one pairing suits a chart where sessions have shape. EURUSD M15 gives a workable rate of marks. On M5 the quick average chases every tick. On H1 a crossing becomes a once-a-day event worth looking at.
What can go wrong
A crossing arrives after the move that caused it.
In a range the two averages cross repeatedly.
The colours chosen make the marks easy to misread.
No filter checks the crossing at all.
Copy the compiled Scalper vault Indicator file into your MQL4/Indicators folder, and the MT5 build into MQL5/Indicators, then restart the terminal and drag it onto a chart. The step-by-step guide with screenshots is at how to install MT4 and MT5 indicators.

FAQ
Why is the Scalper Buy arrow yellow?
It is an unusual choice, and the shape is what matters. Arrow code 233 points upward for a buy whatever tint is applied to it, so read the direction from the symbol rather than the colour.
What does the gap between FastEma 5 and SlowEma 21 achieve?
It cuts the number of crossings. Four times the length between them means the quick average has to move a long way before it clears the slow one, which filters out most small wobbles.
How does FastEma 5 get its very first value?
From the close of the first bar on the chart. Both recursions start there rather than at zero, which stops a spike climbing out of the left edge when the chart first loads.
How is the Scalper Sell arrow positioned?
Fifty percent of the candle’s high-to-low distance above its high. A violent bar therefore pushes its mark further out, which keeps the symbol readable on any symbol without a point setting.
Are results guaranteed?
No. Trading involves risk. Results are not guaranteed; past performance is not indicative of future results. Use the Scalper vault Indicator as one input. Always backtest before trading live.
