I pulled this off of another Broker's website as to why you should trade with them. Interesting about the price/liquidity providers manipulating your trades. The finger points three ways: The Broker, The platform, and the price/liquidity providers. The platform can easily collect data and profile your account and pass this information to the price/liquidity providers. The price/liquidity providers can also get this information handed to them by your broker. Perhaps a proprietary platform is a reason to consider going with a broker.
I have been crippled from playing with real money. I am a momentum trader, if I hit my tp, the next position size will compound each win into larger positions. I will do this until I am significantly up or crippled from getting the direction wrong.
