Version 7 of this scalper keeps the rules simple so signals come often. The scalper inside pro v7 indicator draws an 8-bar and a 21-bar exponential average and marks each cross, as long as a 14-bar RSI is not clearly against it: 48 or higher for buys, 52 or lower for sells.
This build ships as a compiled .ex4 for MT4 and .ex5 for MT5.

The maths behind the plots
Averages
`FastEmaPeriod` `8` and `SlowEmaPeriod` `21` exponential averages each start from a simple average of their first bars.
Gate
`RsiPeriod` `14` must read at least `RsiBuyLevel` `48.0` on an upward cross, or at most `RsiSellLevel` `52.0` on a downward one.
Placement
`ArrowGapFactor` `0.6` sets the mark gap as a share of the bar’s range, so big bars get more room.
Putting it to work
Blue over orange shows short-term bias up.
Each lime mark is an upward cross that passed the gate.
Each red mark is a downward cross that passed.
The gate only drops crosses against clear momentum.
No cooldown applies between marks.
Warm-up needs about twenty-two bars.
Alert channels in this build: popup, push notification, email and sound, one message per closed bar.
A gated cross raises one popup per bar through `EnableAlerts`; phone, email and speaker routes stay off until chosen.

Choosing where it lives
Busy sessions on M5 and M15 suit this pair. The hourly EURUSD screenshot shows a handful of crosses a week. On M1 spread outweighs most moves, and on H4 the crosses track short swings.
The downsides
A near-50 gate lets most crosses through.
Back-to-back crosses appear in quiet hours.
Scalping costs eat small moves quickly.
Popups carry every message at first.

FAQ
Why set RsiBuyLevel at 48.0 instead of 50?
The slack of two points lets crosses through when momentum is roughly neutral. Only crosses with RSI clearly against them get dropped, which keeps signals frequent for scalping.
What does ArrowGapFactor 0.6 adapt to?
Each bar’s own high-to-low range. A wide bar pushes its mark further away, a narrow one keeps it close, so marks never overlap the candles.
Is Inside PRO v7 different from other 8 and 21 scalpers?
The core is the same exponential pair. The loose RSI gate at 48 and 52 is what sets this version apart, letting more crosses through than a strict midline filter.
Can an Inside PRO Buy repaint after the close?
No. The cross and the RSI gate use closed bars, and the build never marks the forming bar. A mark stays even if price reverses straight after it.
Are results guaranteed?
No. Trading involves risk. Results are not guaranteed; past performance is not indicative of future results. Use the Scalper Inside PRO v7 Indicator as one input. Always backtest before trading live.
