Screener results make little sense

I am very very puzzled, when the running hte following code on weekly timeframe for UK stock I see unexpected results eg Capricorn Energy (CNE)??

Very greatful is someone is able to provide some insight.

// ================================================================================
// TIMEFRAME: Daily
//
// CONDITIONS:
//  c1: 50MA declining — current 50MA below its value 5 bars ago
//  c2: 20MA trending higher over last 5 bars — all 5 increments rising
//  c3: 20MA < 50MA < 80MA — MA stack in order
//  c4: High above upper Bollinger Band — breakout attempt
//
// OUTPUT COLUMNS:
//  none — simple pass/fail screener
//
// INDICATORS USED:
//  - 20MA, 50MA, 80MA (daily)
//  - Bollinger Bands upper (20 period, daily)
//
// KEY CODING NOTES:
//  - c1: ma50 < ma50[5] — 50MA lower than 5 bars ago
//  - c2: checks each of last 5 bars rising — ma20 > ma20[1] etc
//  - c3: ma20 < ma50 AND ma50 < ma80
//  - c4: high > BollingerUp[20](close)
//  - No illegal line breaks — all compound conditions on single lines
// ================================================================================

// c1: 50MA declining — below its value 5 bars ago
c1 = ma50 < ma50[5]

// c2: 20MA trending higher over last 5 bars
c2 = ma20 > ma20[1] AND ma20[1] > ma20[2] AND ma20[2] > ma20[3] AND ma20[3] > ma20[4] AND ma20[4] > ma20[5]

c3 = ma20 < ma50 AND ma50 < ma80

// c4: High above upper Bollinger Band — breakout attempt
c4 = high > bbUpd
