Your indicator works with MetaTrader 5 as well as TradingView. The rules are the same, so it marks the same setups, stops and targets as your preview. The Indicator plan covers both.
Choose MetaTrader 5
On Ready for TradingView, choose MetaTrader 5 at the top. You see Ready for MetaTrader 5, No errors, and Your settings in MetaTrader 5: what you can change in the indicator's Inputs tab. If part of your indicator can't go on MetaTrader 5, that part is named.

One thing can't: rules on 15-second candles. MetaTrader 5's shortest chart is one minute.
Download it
Choose Add it to MetaTrader 5, then Download. If you haven't subscribed, Subscribe opens first, then brings you back. You get one file, named Wildflower and your indicator's name, ending .mq5. It is yours to keep.

Put it in MetaTrader 5
- In MetaTrader 5, choose File, then Open Data Folder.
- Open MQL5, then Indicators, and put the file there.
- Close MetaTrader 5 and open it again. MetaTrader gets the indicator ready as it starts.
- In the Navigator, open Indicators and drag your indicator onto a chart using your indicator's candle size.
- In Inputs, check Broker clock (below), then choose OK.
MetaTrader 5's phone app can't add indicators, so use a computer.
The broker clock
MetaTrader shows your broker's clock, not the market's, and brokers differ. If your rules use a time of day, a session or the daily close, your indicator turns your broker's clock into each market's own time.
Broker clock, hours ahead of UTC starts on Read it from my broker, which works while MetaTrader is connected. Broker clock, daylight saving starts on United States dates. The box in the top right corner of your chart shows the clock it used. If it says Please check, set the hours to what your broker shows in winter, and the dates your broker changes its clock.
Alerts
A pop-up alert shows when a new setup's candle closes (Pop-up alert on each setup). For your phone, install the MetaTrader 5 phone app and find your MetaQuotes ID in it. On your computer, choose Tools, Options, Notifications, enter the ID, then switch on Send each setup to my phone in your indicator's Inputs.
What it draws
- Arrows under each buy and over each sell. Show arrows switches them.
- Entry, stop and target boxes and the lines from your rules, as in TradingView. MetaTrader draws solid shapes, so shaded areas are a lighter colour rather than see-through.
- A box in the top right corner with your indicator's name, how many setups it found and the first and last setup, and, when your rules use a time of day, the broker clock. Its times are your chart's own clock.
Marks are decided when each candle closes, so they never move afterwards.
Update it
Download it again from Add it to MetaTrader 5, put the new file in the same Indicators folder, replacing the old one with the same name, then close MetaTrader 5 and open it again. Charts that have it load the new version.
Does it match?
Choose It's on my chart, then find the setups Wildflower lists on your MetaTrader chart. Times there are your broker's clock. To read a candle's marks, open View, Data Window and point at the candle: Buy setup or Sell setup shows a price on a setup's candle.

If it didn't work
- It isn't in the Navigator: check the file is in MQL5, then Indicators, with its name ending .mq5, then close MetaTrader 5 and open it again. If it still isn't there, open View, Toolbox, and read the Journal and Experts tabs for a line naming your indicator.
- It added, but nothing shows: switch to a chart on your indicator's candle size, then check Broker clock (above).
- A pop-up says a setting must be in a range: change that setting back in Inputs.
- Setups at other times than your preview: check Broker clock (above).

On It didn't work, tell us what you see.
