• "use_risk_per_trade" option added to dynamic lot size (as requested by customers).
  E.g. if you set the "risk per trade in %" parameter to "5" while having 1000$ on account and using "700" safety SL (~7$/0.01 lot), the lot size used will be 0.07 because by having a 49$ SL (7$*7) you indeed risk only 5% of your account.
  
  
• "grid" option added (as requested by customers).
  All grid orders have the same SL and the same TP (which can be trailed).
  If you use the grid, the "Move the entry point with MA?" parameter is ignored and therefore the entry point will remain fixed.
  P.S. my subjective opinion is that, the EA is good as it was originally thought to be (without grid). Yet, it is useful to have the option to play around with the grid strategy on backtests. All sets I send do NOT use grid.
  
  
• "Pause trading after a specific big loss?" option added.
  You can now minimize the drawdown caused by important news like pandemics or wars, news which affect the market for many days but can't be seen in an economic calendar. All you have to do is set the loss at which to pause trading, and the number of days to pause trading. Keep in mind that the loss is per trade is used to trigger the pause, not the drawdown per balance.
  Once the pause is triggered, you'll see it on the Info panel (if "Show info panel?" parameter is set to true).
  
  
• StdDev (standard deviation indicator) parameters can now be seen and changed from EA’s settings.
  
  
• The "Use every tick?" parameter was removed as it was no longer. Since build 1.1, the EA always does checks and calculations each tick during trading hours, and only each 5 minutes when idle (during non-trading hours). The goal is to improve the live trading results by minimizing the effects created by ping, network interrupts, too high CPU usage etc., and by making live trading results more similar to backtesting or other live accounts. In version 1.0 there was sometimes a big difference in trades taken on different live accounts (same set would behave differently). Now it's less likely to happen, and the only reasons for that to happen are not related to the EA (these reasons being slippage, ping, different servers etc.).
  
  
• Fixed a bug in the MT5 version which wouldn’t close trades after the closing period time (4AM in default sets). The bug was present and could be seen in both live trading and backtesting results, and therefore the backtesting results were showing the real results.

Thank you for your feedback, it motivates me continue perfecting the EA.

Hi Alexandru,

I am testing the RolloverScalper on MT5 VPS and get the following messages in the log:

2022.07.27 13:40:54.692    Rollover Scalper EA MT5 (GBPUSD,M5)    cannot load indicator 'Moving Average' [4302]
2022.07.27 13:40:54.692    Rollover Scalper EA MT5 (GBPUSD,M5)    cannot load indicator 'Standard Deviation' [4302]

On one server they come repeatedly every 10 sec, on another server this  stops and ther come the following messages:

2022.07.11 22:55:40.731    Rollover Scalper EA MT5 (GBPUSD,M5)    CTrade::OrderSend: buy limit 7.47 EURCHF at -1.00504 sl: -1.01204 tp: 1.00457 [invalid price]

There no such messages in the journal of the terminal befor synchronizing. The named indicators are installed on my terminal:

I limited the "max bars in chart" to 50000 in the settings.

What may go wrong?

Sincerely Ulrich

P.S.

I really appreceate your informative and clear hints on the telegram channel!

It seems that you haven't updated the EA to the latest version (1.2). This error was happening sometimes in the previous versions but I fixed it completely in the latest version.

It is the actual version 1.2

Thanks for your quick and deligent answers, but the errors keep repeating every 10 sec on the VPS:

2022.07.27 15:28:30.227    Rollover Scalper EA MT5 (GBPUSD,M5)    cannot load indicator 'Moving Average' [4302]

The screenshot was from my desktop, where everythig runs smooth (the backtests with HF3 are amazing!). The VPS from MQL5 has no screen ;-). The errors jus occur on the VPS, not on desktop.

 The CPU load of VPS shows 0%, memory used 144 MB, on disk 410 MB used. Other EAs run on that VPS, even in parallel with RolloverScalper. The errors occur also if RolloverScalper is the only one on the VPS. Please double check, I can send you logfiles etc as you need (shall we proceed as PM?)

And: Yes, you are right, the "Invalid Proce" errors came from the old version.

I Got news on this issue:

At first I want to thank Alexandru for is quick and intensive dialog with me.

Second: It was not a configuration problem caused by me, all symbols and the config if MT5 and RolloverScalper were OK.

But there is an issue with MT5: These messages [4302] can occur although you have the named symbol in your market watch, if you never loaded a chart with it to your terminal!

So there is a workaround, if you have the complained symbol on your market watch and the message [4302] appears in the log of your MQL5 VPS (and not on the desktop!), just load a chart with the complained symbol to your terminal and then press "migrate" to synchronize the VPS with your desktop. you can even close the chart and migrate again, it still works.

Uff, this was heavy stuff, I go to bed now.

Correction: You have to place any EA on the chart to make the MQL5 VPS load it once. So you have to do the following if you are using MQL5 VPS together with Rollover Scalper (and some other Multicurrency EAs I expect):

1. Open one chart for every pair that you have in the "Pairs to trade" list

2. place any EA on every chart (with e.g. 0.01 lot size or a dummy EA that does not really trade) to make MQL5 VPS load the chart

3. Press "Migrate" on the VPS tab of MT5 Desktop terminal

4. Close the additional charts again (leaving just the one chart GBPUSD M5 chart with Rollover Scalper)

5. press "migrate" again

Thanks a lot Ulrich! Your previous message (from 29th July) already helped some people and this one will be helpful too.

Hi! Just PM me on MQL5, that's how everyone else is doing.
I sent you the link to the telegram channel in PM.
