(x) Ticks
Many advanced charts have an (x) ticks facility. A tick represents a transaction between a buyer and a seller at a given price (and volume, except in FOREX). In the (x) ticks chart each candlestick shows the price variation of x consecutive ticks.
The (x) tick chart is not time-based. Therefore, each currency pairing in our trade list will close at different times. Moreover, the bars in an (x) ticks view are representations of transactions, and their frequency is variable. For example, over one period we may have 50 bars, and in another period of the same timeline, we could have 75 bars.
Backtesting
Backtesting of multiple currency pairings is the best way to determine if (x) ticks provide suitable trade opportunities for the individual. The example below shows EUR/USD 30 minute bars with one trade entry opportunity in the leg shown.

The chart below uses the (x) trade setting with x being 3,000. In this leg example, two trade opportunities are available. However, this is not to say more trade entries exist with (x) ticks as it all depends on the timeline set (above) or the ticks set (below).

How many (x) ticks
How do we select the (x) number of ticks to view? As with the classic intraday time-based view, this is a personal choice but one which must be mostly proportional to market spread and the mean of the bars traded being a suitable size. If we use 3000 ticks in EUR/USD for example, the leading price action of using 3010 or 2940 will not alter, but the trade opportunities could be significant.
Based on Bob Volman’s day trading with 70 ticks we backtested higher amounts divisible by 70. Some areas of the test are subjective as to whether we would or would not have entered a prospective trade.
Lower timeframe
In the lower timeframe (or tick frame), 1470 and 2940 ticks provided, for us, the best results over a wide range of tests. Tick bars do not correlate well to traditional time-based bars. However, our ticks above would at certain times of volume provide similar representation to 5-minute and 10-minute bars respectively.
Higher intraday
Our favoured higher (intraday) tick frame is 4410 ticks; this equates closely to the half-hour bars on a standard time-based chart. The image below is a 30-minute chart superimposed on a 4410 tick chart over the same period.
In the first half of the image, the ascending 30-minute bars are on the left and in the second half of the picture, the tick bars descend on the right. Those proficient in price action identification will notice a tick bar entry opportunity in both the ascent and descent that is not available to the 30-minute bars.
