I would like to know if it is possible a script (or something else) that sends an alert when, an asset of a watchlis, t breaks or the previous relative maximum or breaks the previous relative minimum in the 15 min graph?
I consider a candle's relative maximum always, in this case 15 min, exceeds the maximum of the previous candle in a downward trend and relative minimum whenever the candle breaks the minimum of the previous candle in an upward trend

I would like to run, if possible in Metatrader


PS:excuse me for my bad english

For that you can create an indicator with an audible or visual alert. Simple to do IF I understand your requests:
-Define the trend.
-Compare the extremes of candles.

Thanks Orderbook for the reply but i don't understand anything about programming .... ☹️. Do you think you can help me, please??

If it’s for MT4, I’ll give you the executable file.

Orderbook,

Yes it is for MT4, thanks I will wait

1-What are the assets on your Watchlist?
2-How do you define the trend (with Moving Average, Higher & Lower, etc...).Is the trend binary, rising or falling or do you consider range periods.
3-Audio or visual alert ?
4-Relative maximum, just to make sure I understand : If the last 10 candles are in downtrend and no new higher, then candle 1 has its high price higher than the high price of candle 2, so you want an alert, is that right ?

HI Orderbook,

1-What are the assets on your Watchlist?

The assets are forex (usdjpy, usdchf, usdcad, nzdusd, nzdjpy, nzdchf, nzdcad, gbpusd, gbpnzd, gbpjpy, gbpchf, gbpcad, gbpaud, eurusd, eurnzd, eurjpy, ejp, cad, ejp and eur , audusd, audnzd, audjpy, audchf, audcad) and indices (NDX, SPX, DOW, DAX, GOLD)

2-How do you define the trend (with Moving Average, Higher & Lower, etc...).Is the trend binary, rising or falling or do you consider range periods.

To define the trend, use the dow theory with higher highs, higher lows, lower low and lower high.

3-Audio or visual alert ?

The alert if it can be better visual and audio

4-Relative maximum, just to make sure I understand : If the last 10 candles are in downtrend and no new higher, then candle 1 has its high price higher than the high price of candle 2, so you want an alert, is that right ?

I leave a drawing attached, I think it might be easier to understand what I want with it.
In other words, whenever in the 15 min in an upward trend a Higher Low is broken I receive an alert and whenever in a downward trend a Higher High is broken I receive an alert.

I hope I made myself understood despite the bad English

Thanks again and any questions say
