Please tell us more about the risks you will take. You talk about 1:200 leverage and 10x profits as tp. That means that you want to be able to catch a 5% movement on the right side, however a 0.45% movement against you will kill your account, along with the money in it.
Forex when done by professionals is something that yet not always works, and they use tiny or no leverage (no more than 1:3, usually).
1:200 is not a medium leverage, it's a huge leverage.
I also think that people should be able to know in real time how much of their founds you are losing.
If ppl know in real time how much equity goes down they will want to withdraw all at the same time. Normal reaction. But the DynaGrid needs to continue to run while in deep minus as thats the whole point of a grid. Google Forex Grids. And grids are hard to deal with but that's my daily job.
A 0.45% movement won't kill the account. I guess you misunderstood. As I wrote, hedging is used and even without hedging its pretty safe. Example: all open orders are lets say short as all long positions just have cashed in. Directly after that the rate goes up by 5%. The account is still safe as 5% has been expected to happen and thus is calculated into the margin. But before we reach a 5% change automatic hedging will kick in (buy lots of long positions) to push the margin up. Hope that makes sense.
With 10.000 USD start capital a 0.5 lot will be closed once it reaches $10-20 profits. Then repeat over and over again. Small gains with low risks using lots of trades. That's how it works.
1:200 is medium leverage as today you can use 1:3000 if you like with FXGlory, 1:2000 with Exness or 1:1000 with InstaForex. Scalping normally uses these high leverages. And there is nothing wrong with that as long as you know what you are doing and have your risk management numbers worked out.
