This is upgraded version of existing Lot size Calculator from melodicfish. I added CZK as a new base currency and translated the whole user interface into Czech language, so this version is made mainly for people from Czech Republic.
Here is the original code description from the original creator: This is a public release of my Lot Size Calculator. I received a request for the code from a user so I am republishing the script so I can make it public (TV doesn't seem to give me the option to simply make it public once published ). This is a very simple script to use. Simply choose your entry level and stop level on the chart and the indicator will calculate the lots. You can change your account risk and base currency units in the settings along with changing the scaling of the calculation to adjust the results with the lot sizing units of your broker. This allows the calculator to be used with CFDs, forex, Gold, etc.. Hope it helps in your trading it has been the single most useful tool in my trading as it has helped me always keep my risk locked up and on point that is why I released it. One final quick note: Remember you can save your settings for your own account size and risk so you do not always have to modify the defaults when loading the script. Just a ease of use tip. I only add the script to my chart when I am about to take a trade so it is helpful to have everything set up in advance.
As i said, the whole user interface is in Czech language, but you can find exactly the same indicator in english language under the name Lot Size Calculator by melodicfish. So i hope i don´t need to provide english translation here.
