"A mistake could fire an order for every incoming tick" that's was scary. If in easy language you set your strategy to buy have max one open position in any direction or every symbol to have maximum 2 open position, could that still happen?
Yes, it could still happen. With the indicator approach to buying and selling there is no "strategy" and no strategy safeguards, it needs to be coded. Maximum number of positions simultaneously open would likely be a user input. The code would need to track entries and exits to control this.
Thanks for head up. And what is order objects and how to creat them for a strategy. Any example or links that explains these details ?
There is plenty of information and examples on the TS support forums. You could spend many hours reading. A search of Order Object Example on that forum should be more than enough to get you started.
Do you have any experience with Muticharts, how Power Language compare to easy language? they seems wanted to copycat everything Trade-station does ....
Yes, I do. While Power Language and Easy Language are similar syntactically, there are differences in implementation. Operationally, the products have many differences. MultiCharts offers C# as well.
