**Pre-Amble**

Well, it might not be easy to understand those values using TradeStation Help Documentation, because I think there is not satisfying explanation.

**What is and How to use them**

Remember, that 3 of them (**MinMove**, **PointValue** and **PriceScale**) are important parameters, and they should be provided by Platform. Other reserved words (**Point**, **BigPointValue**..) are just calculated depending from those 3 values, so, you only need them.

## PriceScale

1)

– This is a pre-determined parameter (Platform gives you specific ** PriceScale** **PriceScale** value per symbol), you dont need to manually determine it. **PriceScale** is a number (i.e. 100) which represents the fractional portion of a full point move for a symbol.This is not obtained by calculations, instead this is a FIXED parameter and different symbols have different **PriceScale** (Platform provides those variable numbers). ** **I mean, how many digits are after dot. For example, many stocks have like this:

here

is 10000 [5 digits after dot] (This is for i.e. **PriceScale****EUR/USD** )

here

is 100 [2 digits after dot] (This is for **PriceScale****E-Mini S&P**, and I will use this one in future paragraphs)

p.s. You may think, that in these cases, i.e. for **E-MINI** price change happens by 0.01 , but that’s not always true.. let’s discuss it a bit later).

So, remember, what is `PriceScale`

. Shortly, it indicates “how many digits after dot”.

*Point*

** Point** – it is a bit confusing value, sometimes it’s called

`pip`

in forex community. It is **1 / PriceScale**

(but in some symbols, like 3 or 5 digit symbols, that value should be multiplied by 10). For example, for AUDUSD, `PriceScale`

is 100000 , but point it’s `0.0001`

.## PointValue

2)

– This is a what TradeStation automatically assigns depending on symbol. This is a market value of one **PointValue****Point**. For example, one ** Point** of

**E-MINI**(which is 0.01) value is

**0.50**. So, you can say that

**PointValue**

is 0.50 for **E-MINI.**

## MinMove

3)** MinMove (Minimum Movement Amount of Points) **– we should remember the difference among these one for any symbol:

**Minimum Movement in price****Minimum Movement in contract value****Minimum Movement Amount of points ( <— only this is called MinMove)**

** MinMove – **This is a pre-determined parameter (Platform gives you specific

**MinMove **

value per symbol). For example, as I’ve mentioned in the beginning, one **E-MINI**Point is

**0.01**( and

**PointValue**

is **0.50**as we said) , but on the chart, you will see that price doesnt change by 1 point (

**0.01**increment), but it changes by 25 (

**MinMove**

) points, which is **0.25**increment (call this one

**Minimum Movement in price**).

Let’s summarize (for example: **E-MINI )**

– one **Point** (of symbol price) is: **0.01**

–

is: **PointValue ****0.50**

– `MinMove`

(**Minimum Movement amount**) of points is: **25**

– **Minimum Movement in price** is: **0.25** (lets call it **TickSize**)

–** Minimum Movement in contract value is:25( MinMove) * 0.50(PointValue) = 12.5 **(lets call it

**TickValue**)

*p.s. BigPointValue*

** BigPointValue **– This is nothing special. Platform just automatically calculates and gives you how much value (per contract) has 1 full point move. This is: amount of Points

**in 1 full point (a.k.a.**

`PriceScale`

) *****

`PointValue`

.For example, for

**E-MINI**, it is : 100 (because

**is 100 ) * 0.5 (**

`PriceScale`

**) = 50**

`PointValue`
