Calculation of Money from entry and exit of a trade..and more

Just want to calculate at a distinct bar(the bar is one between open time or close time) the value of points/money of this trade!

Searching for this formula:
ProfitInMoney= (Open-close+.......)*.....
Is there a same formula for points for every different leverages and lotsizes?
When I have a trade with 1 lots or 0.01 with 1:500 or 1:100 i have the same point difference...but which value to write in a trade manager?

Inserted Code
double entry_price     = Open[0];      // or whatever you want it to be
double exit_price      = Close[0];     // or whatever you want it to be
double volume_in_lots  = 0.01;         // microlot (or whatever lot size you want)
string symbol          = Symbol();     // or whatever symbol you want
double profit_in_money = (exit_price - entry_price) / MarketInfo(symbol,MODE_POINT) * MarketInfo(symbol,MODE_TICKVALUE) * volume_in_lots;

entry_price and exit_price can be any two price levels that you want to calculate the monetary value between.

The above calculation should work universally. Leverage is irrelevant; it merely determines how much margin (which equates to money in your account) that you need to open a position.

Probably should check for divide by zero error but I'll leave it to you to do that.

Hanover, you have a small bug in your logic.

@all: Before multiplying with MODE_TICKVALUE you have to divide by MODE_TICKSIZE. MODE_TICKSIZE is always a multiple of MODE_POINT. Usually the relation is 1:1 but that's not always the case, especially for CFDs.
Inserted Code
PL = priceDiff / MODE_POINT / MODE_TICKSIZE * MODE_TICKVALUE * volume

What does that mean? It means there are some rare instruments where MODE_POINT is not equal to MODE_TICKSIZE, e.g. an instrument is priced in 0.05 increments. Many years ago it was the typical way to quote stocks etc.
It takes blood, sweat and enough tears to wash away the blood.

Thank you...very well explained!

Thanks for the heads-up, but in that case I think your calculation should read:
Inserted Code
PL = priceDiff / MODE_TICKSIZE * MODE_TICKVALUE * volume
Can you please confirm? Dividing by both POINT and TICKSIZE doesn't seem right to me. Although the inflated profit is appealing.

hey hanover..... this might be off topic...... started to mention something similar last night but decided against it......

the need for ticksize is to adjust tickvalue to it's standard constant..... tickvalue changes due to the price change between 2 ticks..... you can verify that in seconds with 1 line of print code....

if the price jumps 10 pips in a single tick, the tickvalue would be 10 times greater.... the ticksize division of 10 returns tickvalue to it's constant.... the same logic holds true if price moves 1/10 of a pip in a single tick.....

all in all, for some reason i have never been able to get the individual components to always equal the order profit.... maybe 10% of the time its a couple pennies off..... quite possibly it's just a digit rounding issue.....

below is the easy to read script..... maybe yall can see my error.... see if the 'o' and 'p' columns match......h
//----

Inserted Code
p = (OrderClosePrice()-OrderOpenPrice())*((MarketInfo(OrderSymbol(),MODE_TICKVALUE)/MarketInfo(OrderSymbol(),MODE_TICKSIZE)))*OrderLots();

//---- edit added screen shot of common differences in column o and p

Of course you are right. MODE_TICKSIZE is already an absolute double, not a simple multiplier (an int). Comes from me not testing what I write. Thanks :-)

Hayseed,

TICKSIZE is always constant, as far as I know, and is generally the same as POINT (except in rare instances, as emmzett points out. I hadn't previously encountered this, as I tend to work only with the majors). I believe the reason for the small discrepancy between your columns O and P is that, whenever you are trading a pair XXXYYY, and YYY is a currency different to your account deposit currency (say ZZZ), then TICKVALUE changes as price moves, because it's used to convert YYY back to ZZZ, and the YYYZZZ exchange rate will have almost certainly changed between the opening and the closing of the position.

To explain using MQL4, what you're effectively doing is:
open_value = open_price / TICKSIZE * tickvalue_at_time_of_close * volume;
close_value = close_price / TICKSIZE * tickvalue_at_time_of_close * volume;
profit = close_value - open_value;

Whereas I expect if you were to save the value of TICKVALUE at the time the position is opened, and do the following:
open_value = open_price / TICKSIZE * tickvalue_at_time_of_open * volume;
close_value = close_price / TICKSIZE * tickvalue_at_time_of_close * volume;
profit = close_value - open_value;
then any discrepancy should be solely due to rounding.

If YYY and ZZZ are the same (for example, if you trade EURUSD and your deposit currency is USD) then there shouldn't be any discrepancy.

There may be additional reasons that I'm unaware of, but I'm pretty sure that's it.

David

For example, performing a dump of EURAUD, its tickvalue is the same as the current AUDUSD exchange rate (0.68514), as the deposit currency is USD:

hey hanover..... ..... i never thought of the reverse back to usd conversion factor..... you almost have to be correct....

the reason i did not post anything last night was because my work on it was from long ago and half forgotten.... not to mention never figured out down to the penny.....

just as you said, as far as i remember every xxxusd trade would be correct.... anything else had a high chance of being a few cents off.....

hope your trading is going good..... and your fire extinguishers are fully charged.....h

hey Hay,

It makes sense when I think about it. Suppose I want to buy EURAUD, which means that I'm 'selling' AUD to buy EURos at the EURAUD rate; but if my deposit currency is USD, then I need to somehow convert enough USD in my account to (electronic) AUDs beforehand, to provide some AUDs for me to 'sell'. Hence the AUDUSD rate conversion that's built into TICKVALUE.

Then the reverse sequence applies when I close the 'position'.

Of course in reality I'm not buying or selling anything tangible, it's all just a big electronic video game. Until I (hopefully) withdraw my profits.

Anyway, I hope you had a great holiday, all the best for 2020.
