Does any broker for the Colombo Stock Exchange (CSE) allow self-trading online for free or with low deposit?

Hey everyone, I’m new to trading on the Colombo Stock Exchange (CSE), and I’m trying to figure out how brokers work here. I prefer self-trading (no advisor or person-to-person interaction) and want to use an online platform to execute trades. However, I’m a bit confused because it seems like most brokers require a minimum deposit (like 100,000 LKR or more) just to get access to their trading platforms.

For context:

On platforms like Binance, you don’t need to "pay" the platform to execute trades; you just fund your account and trade. Is there any broker in Sri Lanka that works similarly, where I can start with little to no deposit and trade online without extra fees for platform access? I’ve heard of Atrad being widely used, but is there any broker that gives access to it without these high minimum deposit requirements? Or are there alternatives?

Would appreciate any recommendations or clarity on this—it’s been a bit of a headache trying to figure it all out!
