It’s a good trading system. I just want to know what calculations you make to use this much leverage. I have never been able to use leverage more than 1:5.
So not sure what you mean by 'using leverage'? The amount of leverage available to you depends on your broker and the regulation they are part of (you know if they are US regulated, or if they are CySEC regulated, or if they are FCA regulated, or if they are ASIC regulated, or if they are part of some kind 'overshore regulator' - the latter one usually allows for the most leverage. You can google those different regulations and find out what your broker is part of (where you live might in some cases also limit you of certain choices, for example if you're from US, your choices of brokers are more limited).
And then, for me leverage itself is not the most important thing, what's important is the position sizing. Leverage and margin rules do control what kind of maximum position sizing you can use on your account, but with position sizing one controls the risk (too large position sizing can be called over-leveraging and is very very dangerous - but it's not leverage that forces a trader to adjust your position sizes too large, it's the trader him/herself. However, with larger leverage it is possible to take too big positions and therefore the different regulators do regulate maximum leverage, to 'save people that don't know how to position size correctly from destroying their accounts and money'.
Hope this helps to understand my view.
