Thanks! I will look what can be done.

The thing is, the tick_value reported to MQL4 is wrong :-). That's the problem.

i explained this Tick size issue with coinexx and turnkey and they corrected their configuration 👍, PSC works normal on their platform now.

Wow! That's great!

Hi!

Is it in MT4 or MT5? What type of account do you have with them? What is your account currency?

it is Demo MT4 and account type "Raw spread" , account currency is USD.

OK. In theory, I could circumvent this by detecting that quote currency != account currency but the reported tick value = 1 account currency unit. Then, the PSC could find the actual conversion pair (USD/JPY in your case) and then calculate the correct tick value.

However, this wouldn't work in M4Markets, because their misconfigured server reports Base Currency as AUD for nearly all currency pairs, even for those that have nothing to do with AUD (e.g., for EUR/CHF). So, searching for a conversion currency pair will fail based on Base/Profit Currencies.

It could be further circumvented by analyzing the symbol name, but I don't really like this way - it is slower and not foolproof due to prefixes/suffixes.

oh ok , thanks for investigating this issue , appreciate it.

yeah making PSC slower and inefficient in calculation for just one broker doesn't worth it for sure.

i have just noticed there is same issue in two other broker Turnkeyforex and coinexx , but not in all JPY pairs and only EURJPY!

and the mt5 version works correctly.

and its not only PSC , most other tools/EAs from other developers also have same issue here.

On those two other brokers, is there any output in the Experts tab of the Terminal subwindow? Like about the PSC failing to retrieve a reference pair?

when i reload PSC:

but for other pairs is shows same log , so no , nothing.

on Turnkey when i check EURJPY(has problem) specification it has a tick value/size field. but on same broker USDJPY doesnt have this field and PSC calculates UJ correctly.

Runwise EA also had this problem, here is their respond:
We’ve had a look at it. The broker isn’t setting the Tick Value correctly. You can see the tick value in CONFIG | Risk / Lots. It’s more wrong on JPY but wrong on other non-USD pairs. When this value is incorrect then can’t work lots from risk pips.

Note, Tick Value is returned by MetaTradre’s MarketInfo() function and it’s the broker’s responsibility to return the correct values: https://book.mql4.com/appendix/marketinfo

You’ll have to either use a different broker or set lots directly in CONFIG | Risk / Lots

here is M4markets respond after i told them it is probably tick value that causes the issue:

"Please consider that we cant be responsible for the correct functionality of any EA as we are not the developers or sellers and we have no relation with coding of any expert advisor. Each EA user is responsible for that.

However as a gesture of goodwill we have checked internally and we confirmed that our configurations on our FX symbols are correct.
No matter what tickmill or anyone is doing on that please consider that if any instrument is on Forex calculation then tick value and tick sizes are automatically being ignored from settings.
Oppositely by having your configurations available for your clients when the open the specifications of any instrument it can be considered as an advantage, because tick size on USDJPY is indeed 0.001 and tick value is indeed 100 JPY."

im wondering , can PSC take the tick value into calculation to solve this problem?
