Privacy while trading

Dear friends,

I would like to know how do we make sure no one is snooping at our trade strategies from inside the brokerage house. Currently I feel safe at icicidirect but am planning to move to something else as the brokerage charges is very high. But I am worried someone might snoop and try to replicate my trades which might make my strategy ineffective.

Hope I am not the only one who thinks like this.

So far what I heard that cheap brokers hedge against our position to get profitable.
Hope reputed one will not do that.
You can look into the direct market access notes at NSE. I think that's safe. But it's for institutional traders.

I'd be more concerned about price, platform and data feed manipulation than brokers knowing our strategy.

Telltale signs of this include:
(a) inexplicable & sudden price spikes (not regular spikes),
(b) platform constantly freezing & disconnecting at crucial times,
(c) candles that appear and disappear intraday but look okay EoD,
(d) prices that don't seem to match intraday,
(e) stop loss hunting, etc.

That is why choosing a reputed broker is important. Just as brokers do your KYC, you should also do the broker's KYC.
