Most traders will host their cTrader automated strategies (cBots) on a Virtual Private Server (VPS), these servers do not come cheap and the memory or RAM as it is known can add to the cost. This tool will help you keep your costs down and also tell you if you need to add extra memory.
THIS PRODUCT ONLY CLEARS THE MEMORY USED BY CBOTS AND INDICATORS USED BY ALGOHOST
IT DOES NOT CLEAR THE MEMORY USED BY THE CTRADER DESKTOP PLATFORM
Backtesting & Optimisation
When you run backtests and optimisation of your cBot settings there can be large amounts of memory left unused, this tool will release this memory by clicking on the Boost Memory button.
Memory Usage with cBots
The latest version of cTrader has isolated the RAM that is used for your cBots, this was done so that a rogue algorithm cannot freeze the trading platform and stop you from trading, the process is now called algohost and is different from the cTrader process. The memory manager will now clear the unused memory for the algohost processes.
There will be multiple algohost processes running for each cBot.
So what happens when your computer runs out of memory (RAM)?
When your computer runs out of memory, your computer will start to use the hard drive space for "Virtual Memory". The problem with this is that your hard drive read/write speeds are much slower than the RAM read/write speeds. You will notice your hard drive activity LED constantly flashing, and your computer will start to run slowly. The more "Virtual Memory" is used, the slower your computer will run.
Do You Need a Large Amount of RAM on the VPS Server?
The answer is a simple "NO", there are many things you can do to reduce the amount of memory being used by your PC or Server so that your Algorithms can run smoothly. Watch the video below which will explain how you can reduce memory usage without having to pay out large amounts of money each month.
cTrader cBot Memory Manager
The memory manager (booster) will assist you in keeping your cTrader trading platform memory down to a minimum for a smooth operation.
Excel Reports
All the log files are comma-delimited CSV files which are perfect to import into excel and to create a historical graph of memory usage, with this information you can decide if you should upgrade your RAM on your machine or not. Every day a new log file is created as shown below.
Each time there is a memory boost an entry is added to the log.
