Boom Index Spike Pattern - indicator for MetaTrader 5

DATA STRUCTURES

struct PatternInfo {
  datetime time;   // Time of the pattern
  double entry;    // Entry price (open of 2nd candle)
  double high;     // Highest high of the 3 candles
  double low;      // Lowest low of the 3 candles
  bool mitigated;  // Has price returned to entry level?
};

CArrayObj activePatterns;
```
We use a struct `PatternInfo` to track each valid pattern and store it in an array. This helps avoid repeated processing.

ON INIT FUNCTION

int OnInit() {
  IndicatorSetInteger(INDICATOR_DIGITS, _Digits);
  ArrayInitialize(activePatterns, 0);
  return INIT_SUCCEEDED;
}
```
We set the indicator precision and prepare our array.

```mq5
for (int i = limit - 3; i >= 0; i--) {
```
We loop through candles and look 3 bars back.

```mq5
if (isBullish(i+2) && isBearish(i+1) && isBullish(i))
```
We check if the last 3 candles fit the spike pattern: Green-Red-Green.

```mq5
double high = MathMax(MathMax(High[i], High[i+1]), High[i+2]);
double low = MathMin(MathMin(Low[i], Low[i+1]), Low[i+2]);
double entry = Open[i+1];
```
We extract high/low for box and the entry level from the 2nd (middle) candle.

```mq5
PatternInfo *pattern = new PatternInfo;
pattern.time = Time[i];
pattern.entry = entry;
pattern.high = high;
pattern.low = low;
pattern.mitigated = false;
```
Create and add this pattern to our list.

```mq5
string boxName = "Box_" + IntegerToString(Time[i]);
ObjectCreate(0, boxName, OBJ_RECTANGLE, 0, Time[i+2], high, Time[i], low);
```
Draw the rectangle (box) from the 3-candle pattern.

```mq5
string lineName = "EntryLine_" + IntegerToString(Time[i]);
ObjectCreate(0, lineName, OBJ_TREND, 0, Time[i], entry, Time[i] + PeriodSeconds() * EntryLineLength, entry);
```
Draw the entry line from the 2nd candle’s open forward in time.

MITIGATION CHECK (ON EACH TICK)

Loop through all patterns:
```mq5
for (int p = 0; p < activePatterns.Total(); p++) {
  PatternInfo *pt = (PatternInfo*)activePatterns.At(p);
```
If not already mitigated, check:
```mq5
if (!pt.mitigated && Low[0] <= pt.entry)
```
If current price hits the entry level:
```mq5
pt.mitigated = true;
ObjectDelete("EntryLine_" + IntegerToString(pt.time));
```
Delete original long line.

```mq5
ObjectCreate(0, "MitigatedLine_" + IntegerToString(pt.time), OBJ_TREND, 0,
pt.time, pt.entry,
Time[0], pt.entry);
```
Create a short line showing where mitigation happened.

HELPER FUNCTIONS

### Check Bullish/Bearish:
```mq5
bool isBullish(int i) {
  return Close[i] > Open[i];
}

bool isBearish(int i) {
  return Close[i] < Open[i];
}

This indicator is simple yet powerful:

• Detects real spike behavior in Boom
• Visualizes smart money entries
• Automatically detects mitigation

You can now test it live on Boom 500 or Boom 1000.
