Indicator Integrator Strat <<<<<< UPDATED with Correction — Strategy by forexpirate

nzdusd equity equitymanagement true balance spreads

Found an error in the orders. Script was making double orders at times. I fixed it. It is tuned as such:

NZDUSD
15 min chart
starting $USD to show 1000 contracts for minicontract with FXCM (start date 3-18 $633 with 1:50 leverage)
Indicator plots ==> Starting equity - (trade gain and loses) - (number of trades) * (spread) = true balance estimate
