Hey fellas! This CC is based on the example I shared here: https://www.haasscripts.com/t/example-position-sizing-based-on-pre-determined-acceptable-loss-stop-loss-size/ Usage:


local acceptable_loss = 100 -- USDT
local entry_price = CurrentPrice().ask -- we buy the ask price
local stop_loss_price = SubPerc(entry_price)

local trade_amount = CC_GetDynamicTradeAmount(acceptable_loss, entry_price, stop_loss_price)
local margin_amount = CC_GetDynamicTradeAmount(acceptable_loss, entry_price, stop_loss_price, 'margin')
local notional_amount = CC_GetDynamicTradeAmount(acceptable_loss, entry_price, stop_loss_price, 'notional')

DefineCommand('GetDynamicTradeAmount', 'Get dynamic trade amount, margin or notional size based on inputs.')

local acceptable_loss = DefineParameter(
        NumberType,
        'acceptable_loss',
        'The acceptable loss amount.',
        true,
        100,
