I find the lot calculation tedious so I just use this script and tell it the dollar amount to use. It then does the rest. This works for any currency.
How-To:
Open a buy position using the desired dollar amount instead of lots.
To use, just drop it onto a chart and set inputs as needed.
Inputs:
- FIXED_DEAL_AMOUNT: Fixed amount to use per trade e.g 100 to open a R100 deal
- USE_SL_ON_BUY: If true then a suitable stoploss will be used, else no stop is placed but can be placed manually after opening position
One can also set a global variable '_Symbol+_MAX_SPREAD' to set max spread limit for each traded instrument.
e.g For EURUSD the global variable would be: EURUSD_MAX_SPREAD
e.g For Nasdaq 100 the global variable would be: Nasdaq 100_MAX_SPREAD
