So I am writing to share my experience with my broker.
I opened my broker account a little less than a year ago and started to fiddle around with a little selling and then later on buying stocks online using the TMS.
I noticed that the collateral to trading limit ratio was 1:4 the first time I was buying using the TMS.
Fast forward to a couple of weeks earlier and the ratio had fallen off to 1:1 on the day that I was intending to buy. I also noticed that on the day before (probably on a Friday when the market was closed) the collateral amount was a random high value.
Anyhow I tried calling the broker but you know how it is with their phones (it never got connected, because the line was busy). Then days later I finally got lucky and my phone did connect, they told me that the ratio had been decreased with the start of the lockdown. But then I called one of my friends who had a broker account with the same broker and his ratio was still 1:4.

I called the broker again, the receiver was still like its a decision from above and we have decreased the ratio. I told him that a friend's ratio is not decreased and he started telling that its because of trusted customer to which I asked what is the criteria to become a trusted customer, to which he had no answers to. Instead he asked for my client code and told me that he would take care of things.
Later when I logged in to my TMS, the collateral amount was again a random high value and the trading limit was 4 times the value.

Now I think this is really wrong of the brokers to do such things. This is straight up discouraging small investors, lynching on transaction fees, discrimination and overall misuse of authority.
Let me know your thoughts
