The tick volume is measured by how much the price is has ticked “up” or “down” in that particular candle bar. So the more people are getting in at the time, the longer the volume line will become. This is because there will be more movement in price action with all of those entry orders flying in. So it makes sense that the volume indicator is, first of all, very accurate, and second has no real lag to it. It is currently showing you what the price action is doing the number of “ticks” on that candle bar. This results in the bar looking like this:
The bid–ask spread is two sides of the same coin. The spread can be viewed as trading bonuses or costs according to different parties and different strategies. On one hand, traders who do NOT wish to queue their order, instead paying the market price, pay the spreads (costs). On the other hand, traders who wish to queue and wait for execution receive the spreads (bonuses). Some day trading strategies attempt to capture the spread as additional, or even the only, profits for successful trades.[18]
Risk management - Rather than looking for one big trade, the way a trend trader might, the scalper looks for hundreds of small profits throughout the day. In this process the scalper might also take hundreds of small losses during the same time period. For this reason a scalper must have very strict risk management never allowing a loss to accumulate.
Day trading is the act of buying and selling a financial instrument within the same day or even multiple times over the course of a day. Taking advantage of small price moves can be a lucrative game—if it is played correctly. But it can be a dangerous game for newbies or anyone who doesn't adhere to a well-thought-out strategy. What's more, not all brokers are suited for the high volume of trades made by day traders. Some brokers, however, are designed with the day trader in mind.
