Current customer of trade-ideas, however I am finding it is not as customizable as I would like with alerting. For example, alerting on indicator crossover events, pretty much any alert that could occur on a 1 minute time frame. They do not offer much for 1m alerting. I am currently experimenting with FW_MOBO with DPO, and would like to generate alerts on this indicator combination. I have experience in programming, and have been working on my own alerting system, however this is very time consuming and tedious..... Not to mention without an expensive data feed subscription, I am stuck using yahoo finance API. With Trade-Ideas price point of $1000 annual. Is there any competition near this price point that allows the customization I am looking for? Does anyone else program their own alerting system? What data feed do you use?
If you're willing to get your hands dirty with some code you can get a realtime feed from https://www.alphavantage.co/ or https://polygon.io/ then you'll have the flexibility to code up any type of alert system you want. I use the polygon WebSocket feed to great effect in my trading system. Even if you don't have any programming skills you might be surprised at what you can accomplish with ChatGPT especially since it's already been trained on the api documentation of the aforementioned feeds.
At one time, I thought about customizing ToS using ThinkScript but found that they didn't update nearly as quickly as Trade-Ideas. There is a reason why TI is more costly, to support the real-time infrastructure to push out alerts in a timely manner.
