Double CCI With SMA Indicator: Fast Against Slow

Written by Dominic Walsh · Published 4 Jun 2026 · Last updated 18 Sep 2026

The double cci with sma indicator runs the same index twice at different speeds. `InpFastPeriod` reacts within half a day and `InpSlowPeriod` describes a much longer stretch. A crossing between them counts only when it happens beyond `InpBuyLevel` or `InpSellLevel`.

This build ships as a compiled .ex4 for MT4 and .ex5 for MT5; the screenshots below come from EURUSD H1.

What the file declares

CCI Fast is the dodger blue line at `InpFastPeriod` bars.

CCI Slow is the orange line at `InpSlowPeriod` bars.

Buy places a lime arrow twenty points below the crossing value.

Sell places a red arrow twenty points above it.

• CCI Fast: line, dodger blue, width 2
• CCI Slow: line, orange, width 2
• Buy: arrow, lime, width 2, arrow code 233
• Sell: arrow, red, width 2, arrow code 234

How it all fits together

Two speeds of the same index

iCCI supplies both readings on typical price, at `InpFastPeriod` `14` and `InpSlowPeriod` `50`. Running one index at two lengths gives a fast line and a slow one that share a scale exactly.

Testing the crossing

crossUp needs the fast reading at or below the slow one on the previous bar and above it now. crossDown mirrors that. Both bars come from completed data.

Filtering by location

A buy also needs the fast reading below `InpBuyLevel` `-50.0`. A sell needs it above `InpSellLevel` `50.0`. That rule removes the crossings that happen while both lines hover near zero.

How to read it

Both lines share one scale, so their distance apart is meaningful.

A crossing far from zero says more than one near it.

The slow line at fifty bars moves slowly, which makes crossings rarer.

Marks sit twenty points off the crossing value, so they trace the fast line.

Alert channels in this build: popup, one message per closed bar.

`InpEnableAlerts` ships on and raises a terminal popup on a closed-bar crossing. This build carries no push, email or sound channel. The guard permits one message per closed bar, so a crossing cannot repeat.

Matching chart to settings

Two speeds of one index need a chart with enough bars for the slow line to matter. EURUSD H1 is the reference chart, where `InpSlowPeriod` at `50` covers two days. On M5 the slow line still reacts within hours. On H4 it describes over a week.

What it cannot do

Both lines read the same prices, so they are not independent views.

The index has no bounds, which leaves a crossing far out with nothing to work against.

Fifty bars of lag means the slow line turns long after price does.

FAQ

Why run InpFastPeriod and InpSlowPeriod together?

Because two lengths of one index share a scale exactly, which two different indicators never do. The distance between the blue and orange lines is therefore meaningful, and a crossing is a clean comparison.

What does InpBuyLevel at -50.0 block?

Every crossing that happens while the fast reading sits above minus 50. Those are the crossings near the middle of the range, where the two lines tangle. The rule keeps marks to places where the index had already moved.

How far are the Buy marks from the crossing?

Twenty index points below the fast reading at that bar. So the marks trace the blue line rather than sitting at a fixed pane height. That makes a sequence of them easy to follow.

Does InpSlowPeriod at 50 lag badly?

It lags heavily, and that is the point of having it. A fifty-bar index describes two days on EURUSD H1. The fast line supplies the timing while the slow line supplies the context.

Are results guaranteed?

No. Trading involves risk. Results are not guaranteed; past performance is not indicative of future results. Use the Double CCI With SMA Indicator as one input. Always backtest before trading live.
