I need your help with this indicator please

Good day everyone
hope you're all doing well

i need your help to make MT4 indicator that draw histogram for the following formula:
Up Candle: (High-Low)+(Open-Low)+(High-Close)
Down Candle: (High-Low)+(High-Open)+(Close-Low)
and please need the output to one buffer

and many many thanks in advance

Hey, I can help with this. You're basically trying to create a histogram that shows
the "size" of each candle based on your formula, right?
Here's a simple indicator that does what you want:
```mql4
#property indicator_separate_window
#property indicator_buffers 1
#property indicator_color1 clrLime
double HistogramBuffer[];
int OnInit() {
SetIndexBuffer(0, HistogramBuffer);
SetIndexStyle(0, DRAW_HISTOGRAM);
return(0);
}
int OnCalculate(const int rates_total,
const int prev_calculated,
const datetime &time[],
const double &open[],
const double &high[],
const double &low[],
const double &close[],
const long &tick_volume[],
const long &volume[],
const int &spread[]) {
for(int i = 0; i < rates_total; i++) {
double range = high[i] - low[i];
if(close[i] >= open[i]) {
// Up candle
HistogramBuffer[i] = range + (open[i] - low[i]) + (high[i] - close[i]);
} else {
// Down candle
HistogramBuffer[i] = range + (high[i] - open[i]) + (close[i] - low[i]);
}
}
return(rates_total);
}
Give it a try and let me know if it works or if you need any tweaks. Also might want
to add different colors for up/down candles if you want it more visual.

It seems you are not aware of it, but your formula doesn't make much sense. Why?

Up Candle:

Down Candle:

You can already see where this goes. It holds:

which results in:

Up Candle:
Down Candle:

You'll notice that the same result for both sides will not yield much information about the market.
