Leverage should ideally be volatility dependent, which is time frame dependent.
So the key inputs to determine leverage are:
1) maximum capital at risk
2) volatility measure
Here's an example (assuming only trading 1 position at a time):
. risking maximum 1% of account per trade
. $100k account
. means risking max $1000 per trade
. lets say we are trading EURUSD
. lets say we use the 60min chart
. lets say we pick the 20EMA ATR as volatility measure, currently at 0.0016,
. and lets say we use as stop such ATR x3
. that translates into 48 pips stop
. which translates into $480 stop for every EUR 100,000 trade.
. then $1000 / $480 = 2.08
. thus under this approach one should trade EUR 208,000 on a EURUSD trade
. which would represent leverage of 2.08 * 1.1186 = 2.33
My ideal leverage is in the 1:1-5:1 range. Think about finding your ideal leverage going through an analysis similar to the one presented above.
