Hello, I'm from Vietnam. I'm an experienced MT4 & MT5 Coder and Forex Trader.
Regarding your project, I completely understand your idea and can finish it quickly, within some hours.
My coded Indy will have all 4 type of Alert (Popup, Sound, Email, Push), can turn off/on any alert method, can set Instant Alert or alert after candle closed. The Alert message contains: Pair, Time Frame, ...
However, for sure, we need discuss about the alert rule, such as when alert ... I found that pretty many Indicators impossible to code alert exactly for a specific rule (and lead to misunderstand between us after the work finished).
So please message me to discuss more.
Thank you and I'm looking forward to working with you!.
