Kripal, I checked with the RF, it seems fine.

Attacking the Myth!
Many beginners believe that brokerage is the most important part of transaction cost, and also that it is deciding factor in profitability for scalpers. Retail pro scalpers understand that it can be the least important factor.
Explicit Transaction costs: comprise the brokerage fees that traders pay to trade, payments to the exchange, commissions paid by traders to brokers, stamp duties, registration fees, and capital gains taxes. Aside from some fixed costs explicit trading costs are usually proportional to the size of the trade involved.
Implicit Transaction costs: are intangible costs that traders pay when they trade. These include the price impact of trades, also called the impact cost, and the bid-ask spread. While costs rise with the size of trades, theyre non-proportional to operating size. They rise for less liquid tickers.
Missed Opportunities costs: These include all exogenous factors to the system. For eg., out of emotions a trader may not be able to act right for a second, and end up executing at higher price. Another eg. is there may be sudden latency in your connectivity and quotes are lagging.
